RUGER SR762 rifle impressions

I recently picked up a SR762 in late November of this year, and am currently evaluating it. ( Rd count is at 140 at this time. A mix of Win Q3130 and LC Xm80 so far)

Please bear with me here, as I'm an M14 guy, and have very little hands on with 7.62 NATO/308 AR's with exception to a few from work.

Here is what I like about it so far.........

1. The rifle is very compact. ( 34 3/4 inches collapsed and 38 inches fully extended)

2. Disassembly is very easy and straight fwd to that of a common AR, other than the piston system itself.......which doesn't require tools to take apart, and put back together again. The extractor spring will fall out on it's own if one isn't careful, along with it's little O ring however.

3. Overall, it is a well balanced stick, and not near as front heavy as I was thinking it might be before picking one up and handling it.

4. All the other components that came with the rifle. ( 3-20rd mags for example). It also came with instruction manual, Ruger lock, front sight adjustment tool, 2 pieces of rail, 3 handguard covers, and a zippered soft case.

5. The iron flip up sights are made by Sampson, are fully adjustable, and have the dual (A2 style) flip up apertures. They positively lock into place as well as lock down when folded. So far, it's a relatively easy task to repeatedly put holes thru "Ivans" out to 300 meters.

6. The BCG, chamber, and bbl are chrome lined with fluting underneath the handguard to save weight. (According to my scale, the empty weight is at 8.6 lbs) Not to shabby for a heavy contour 1-10 in twist hammer forged chrome lined 16.12in tube.

7. The bbl.'s muzzle is threaded, and will allow for a multitude of different style flash hiders, muzzle brakes, as well as a can.

8. The adjustable gas system has 4 settings to allow one to tune it for a wide range of factory or hand loaded ammunition, to include subsonic fodder. It also has the ability to completely shut of the gas system entirely if one desires. Easy to take down, clean, and put back together when done.

9. The hand guard is aluminum, and can be adapted for just about any configuration one desires. ( I personally don't have a use for the " cheese grater" rails all along all sides of a hand guard, and prefer the clean lines of this one in comparison. The little covers that come with it are a nice touch, and are quick and easy to install if desired, as is the 2 sections of rail if they are needed.
The HG also covers up the gas block, thus preventing long armed folks from accidently burning their fingers via contact with the block.

10. The "flat top" rail has plenty of space to mount virtually any type of optic, NVS, etc..etc..... and has the room to mount fwd long eye relief optics if one is so inclined. ( There is quite a few AR fans here, so your all pretty much tracking as to flat top designs.)

12. The "Houge" pistol grip works well for my mitts, and provides for a good grip even when the rifle is soaking wet. (I took it out during the last snow/ice/sleet/rain we were having around here)

13. Reliability: Too early to tell, but so far I've had no issues with it. ( I'm still only using one of the 3 mags that sold with it, but it has fed, fired, extracted, and ejected all 140 rds I have put thru it to date.)
I'm still "at the tip of the iceberg" so to speak, but I don't baby my rifles, and will be comparing the SR762 directly up against my M14S, LRB ARMS M14SA, and M1A-A1 in terms of reliability in adverse weather conditions.

14. Ease of cleaning as compared to a DGI system. It blows DGI out of the water, as the dirty end is not inside the action. Much easier to clean, less time consuming, and doesn't require a full on tear down in the field.

15. I have fired quite a few different semiautomatic 7.62mm chambered rifles before, but this one has less felt recoil than all the others combined. Fast and accurate follow up shots are a breeze and almost as fast as a 5.56mm chambered AR. I'm impressed with how it reacts while the trigger is being pulled, and especially since it comes with the Ruger flash hider instead of a muzzle brake like the Socom16 comes with for example.

16. Unlike the mini14, the SR762 utilizes a common magazine that is easy to find, currently being made, and of good quality. I don't have any metal SR25 mags as of yet, but intend to try a few out with this rifle once they get here.
I have a lot of respect for the decision made by P-mag to move their company out of a state that has recently infringed upon a U.S citizens rights.......but that's a whole other topic.

17. The rifle sports a fwd assist. An important piece IMO.

Here is some things I think they could have done a tad bit better......

1. The Ruger flash hider is all but worthless, and doesn't do a very good job at suppressing muzzle flash as compared to just about any other flash hider out there. Easy fix, but wish that it would have come with a better one.

2. It's black. I suppose that this is a good idea for Ruger, as most folks interested in this type of rifle like belonging to the E.B.R. club.....lol I'm not one of them, but I guess it could have been worse if the only color it sold in was pink.....:p

3. Lack of an ambi safety switch. A relatively low cost addition, and especially compared to a left hand bolt GSR....for example. Easy fix however.

4. The trigger is a tad on the heavy side for the type of rifle it is. Replacing it is not a big deal, but would have liked to see a better one from the factory. Since I only have 140rds thru it so far, it might break itself in as I put more rds down the tube.

Future plans: Pick up a few more mags for it, dump a few hogs with it here and there, and evaluate it as it came NIB for now. I'll add a sling to it, but not add an ambi safety until I retire out of the Army first.
Eventually, I'll try out a few optics with this rifle, and add a can to the mix.
For now, I'll run it as is to get a good baseline for what it can do, and go from there.
Once my oldest boy brings me back my chrono, I'll post MV results with various factory loads.

Notes to folks who are looking at this rifle......

1. Take care when disassembling the extractor, as the spring and 0 ring can fall out via gravity. The plus side is that they don't get near as dirty as a DGI AR does.

2. Some folks may not care for the "milspec" stock, but there is a host of others out there that should suit anyone's needs. ( I'm simply used to this type, as it is almost exactly like the M4 stocks at work.)

Endstate: This is the first AR10 style rifle I have owned, and I believe that it had more to offer than the other factory built AR I was comparing it too. (Sig 716)
I also see Ruger adding to the SR762 line up as they did with the SR556. ( Additional uppers, and maybe other caliber options, such as 243, 260, and 7mm08. for examples)

And now for some questions, as there is quite a few folks here with knowledge concerning AR10 type rifles in all flavors...

I would love to here from others here concerning any positive/constructive advice, opinions, etc concerning these types of rifles.

Optics mounts? ( Burris, Nikon, etc......)
Optics? (Nikon M308, Leupold, Redfield BZ tac MOA...etc...)

Other?

Like I mentioned before..... I'm new to the 7.62/308 AR world, so I'm open to ideas concerning this rifle, and specifically to those who own the SR762 already.

Pics of your 308 ar's would be great.:)

i'd be interested in group sizes as well, if shot for such.

i'm contemplating this rifle as a next purchase and weighing it against others. thanks for the writeup. i agree that the ruger flash suppressor is junk. and would be swapped immediately. the grip and stock would likely have to go as well, although, i'm also used to the m4 style stock. lack of an ambi safety doesn't concern me as i don't run them on an ar. i would likely swap the trigger out for a nicer unit.

thus far, i've read nothing but good things about the ruger. keep us posted with updated reports concerning reliability, function, and accuracy.

No problem once I get my chronograph back from my oldest boy. (Should be right after Xmas or so.

I haven't shot for groups yet, but plan too around the same time I get my chrono back.

Can anyone recommend a good one piece mount for this type of rifle?

Looking for something with a quick detatch/return to zero feature that is precise and repeatable.

Nikon sells one with their M308 scope, and Burris has one as well.( AR-P.P.R )

Any other good quality mounts?

I'm also looking at the AAC 51T flash hider to eventually run tandem with a 762SDN-6 can.

Swapping to a different pistol grip shouldn't be a problem at all.

I'm gonna keep the OEM trigger alone for now and see how it warms up with more rds down the tube, but here is an idea for you concerning a trigger upgrade...... (No hands on here, but might be worth considering)

for a mount, the burris gets good reviews, but i haven't heard much about the nikon. for absolute piece of mind with regard to returning to zero, i would look at the larue mount.


i'm familiar with the geissele units and would likely be the route i go.

Check out LaRue Tactical and American Defense Manufacturing (ADM). I've got mounts from both of them and they're pretty much bomb-proof. If it's important to you, ADM and LT are both American made from American materials and carry lifetime warranties. ADM's adjustable QD system is pretty nifty, allowing the user to dial in the right amount of tension required by his rifle's pic rails.

Optics

You know the drill: mission drives equipment. A good GP scope would be a 1-6x or 1-8x. That would let you dial down for short range shooting, but allow you enough magnification to reach out if you wanted to.

Congrats on the purchase! If you plan to purchase a can, the advantages over DI are HUGE.

If color is an issue, you can always get it CeraKoted. If you ever want to go that route, Jared Harshaw of Harsh Firearms is the man. Check his work out at harshfirearms.com.

Thanks for the review of this rifle. I have one on order and was interested in an unbiased viewpoint.

I currently have an M1a and a converted Saiga in 308.

I have a Burris PEPR mount on a couple of my ARs, I wouldn't hesitate putting one on the SR762 when the time comes.

I have had mine for a couple of months and have put 200 or so rounds through it and I concur with all of Fragouts Pro's/Con's.

http://i30.photobucket.com/albums/c307/ATCDoctor/10-30-2013/DSC00276_zpsbc7a0385.jpg (http://s30.photobucket.com/user/ATCDoctor/media/10-30-2013/DSC00276_zpsbc7a0385.jpg.html)

For those that are interested in group size here's a few pics I took of some groups fired with mine:

This is my shooting area and groups were fired at 200 and 300 yards:

The scope is an old Springfield Armory first generation 4X14X56mm Rangefinding scope with reticules out to 1000 yards. Ammo was my handloads using WC844T and Nosler custom competition 168 grain bullets.
http://i30.photobucket.com/albums/c307/ATCDoctor/10-30-2013/DSC00279_zps67868b21.jpg (http://s30.photobucket.com/user/ATCDoctor/media/10-30-2013/DSC00279_zps67868b21.jpg.html)

Here's a 5 shot group on paper (at 200 yards) that has 4 rounds into 1 inch with a flyer taking it out o 2.25 inches.

http://i30.photobucket.com/albums/c307/ATCDoctor/10-30-2013/DSC00281_zps42fb3bc8.jpg (http://s30.photobucket.com/user/ATCDoctor/media/10-30-2013/DSC00281_zps42fb3bc8.jpg.html)

Here's a 5 shot group on steel (at 200 yards) that's roughly the same size:

Here's a 5 shot group on steel at 300 yards 4 shots into 2 inches with a flyer taking it out to 3:

All in all I like the rifle. Thetrigger pull is what I would characterize as heavy and it makes putting multiple shots into small groups a little challenging.

I always seemed to get one flyer about an inch out from the main group and I'm sure its due to inconsistent trigger manipulation.

Any issues with regard to reliability from yours?

Right out of the box the bolt (sporadically) would not lock back on an empty magazine (regardless of gas setting).

After 50 or so rounds the problem cleared up now it's 100% reliable on setting 2 and 3.

Ruger looks, again, to have done a good job on this rifle. It should be very popular, along with the M&P 7.62 model.

SCAR17S is next on my list, but either the Ruger or the M&P will follow shortly afterward.

Shoot straight.

Outstanding, and exactly what info I was looking for. Thanks to all for recommendations, and especially concerning the various mounts and optics.

Back40, Mac66, and LebbenB. Thanks again for your recommendations regarding mounts.

ATC Doktor: Nice write up and pics. Thanks for sharing them here. A few questions for you.

1. Your buttstock looks a tad different than mine. Can you tell me more about it.

2. What mount are you using under your SAI scope?

3. I have read your posts in the past, and it looks as if your into using cans on various rifles I'm interested in. Ruger GSR and M1A Scout just to name 2 of them. Have you put any trigger time behind the SR762 with a can installed as of yet?

Oily Pablo: I haven't really looked into ambi safety switch ideas as of yet. My plan for now is to keep it as is for the sake of establishing a baseline on what this rifle can do as it came from the factory. My other reason stems from what I do for a living, so want to keep it in place as a simple familiarization concerning the issued M4 I'll be using on an upcoming deployment to Afghanistan.( I'm a career 11B).
Once I retire, my plan is to swap it out with an ambi selector switch, as I'm not only left handed/left eye dominant, but prefer the ambi switch for rapid transition from left to right hand operation while on the move.

As far as triggers go, I know that Timiney (cant spell it) has a decent one, but I'm sure that others also make a good one.
You might find the below link useful if your plan is to swap triggers......

They compare it to the OEM trigger.

For now, I'm gonna run with the OEM trigger simply to find out first hand as to what it is and is not capable of.

It appears that AR15 triggers and selector switches will interchange with the SR762

The outdoor channel link compares the SR762 with the SR556. Although the SR556 is not the most lightweight AR15 type out there, the difference in weight between the above mentioned rifles is around .66 lbs.

1. Your buttstock looks a tad different than mine. Can you tell me more about it.

The stock on my SR762 is a SIG 556 stock I had lying around. The OEM stock on the SR762 was a little "Blah" so I swapped it out.

2. What mount are you using under your SAI scope?

The scope mount is an old Armalite 30mm I had set up on my AR10, I just moved it from one rifle to the other. It works fine and is detachable (via screwdriver) and returns to zero close enough to be acceptable (in my book) returns to zero within .5".

Have you put any trigger time behind the SR762 with a can installed as of yet?

Negative, I have the can, I have the mount, but haven't set it up yet.

I want to make sure there aren't any issues with the rifle yet (it being a new model) before I make any big changes on the rifle.

If I have to send it back to Ruger for any problems, all the aftermarket stuffs gotta come off and it's a pain to get a flashider off that's been rocksetted in place.

I'll put another hundred or so rounds through it before I set it up for the silencer.

fragout
December 15, 2013, 02:07 PM
Good idea in regards to holding off on the can for now. I am thinking along the same lines, as the rifle is still new, and if it needs a trip back to Ruger for any reason, I can honestly narrow down the issue to an all OEM Ruger rifle.

I haven't even messed with the various gas settings as of yet either. (Mine was set at the #2 position when purchased, and have left it there with exception of turning it completely off for a few rds out of curiosity.)

Nice grouping at the 200 and 300 yard mark by the way. I'm still in the "supplied iron sights only" phase at the moment.

Their picture gallery is massive, but I glanced thru it a bit and was impressed with some of their ideas concerning colors, camo patterns, etc...etc......

From the looks of it, the only limiting factor for what they can do is the customer's imagination.

(No hands on here, but might be worth considering)Do not hesitate! Get the Geissele SSA-E without delay! Makes a whole new rifle out of it.

You will NEVER regret it.

:D

And here's what The Truth About Guns had to say about the stock trigger:
Letís start with the trigger. It sucks more than almost any other trigger Iíve tested this year. In fact, I think Iíd prefer the trigger off the Tavor SAR than this one. This trigger feels like youíre dragging it through a gravel pit, and itís creepier than a tea party with Bela Lugosi. When you finally get it to the end of its travel, the force required to hit the break is closer to that of a GLOCK than a .308 rifle. The SCAR 17Sí trigger is equally as heavy, but without the accompanying awfulness.

If you buy this gun, Iíd recommend replacing the trigger as one of the first things to do. While it may seem like an inconvenience, replacing the trigger should be a snap given the wide availability of replacement triggers for the AR-10 platform. Plus, itís just as easy as an AR-15 ó two pins and youíre done.

Check out the warne ar flat top tactical rings. I like them on my ar10. You dont need as much forward offset on the mount on ar10 because the receiver is longer. I put the front ring at the front of the receiver rail and move the scope all the way forward. Not quite nose to CH but close enough. I went with these rings an 2-7 scope to save overall weight keeping with the theme of my mp10. As light and useful as a carrying ar10 can be.

Purchased one on an impulse buy when visiting my LGS.

My impressions mirror the OP's for the most part.

The flash hider can always be changed so that was of no concern.

All my AR's have R sided controls and i'm R handed so again of no concern to me.

My issue was a lousy trigger and replaced it with a Timney 308 and now it's "Just Right".

I placed a Leupold 1.25-4 Patrol with a one piece Leupold mount and like it a lot.

It corrected the things I felt needed correction and am extremely happy with the results.:cool:

The feral pig IS expanding. A sow becomes sexually mature at 6 months and can litter 2-3 times a year with 6-12 piglets per litter. That's a LOT of pigs in a very short time. TX estimates that upwards of 20% of the population must be eliminated annually IOT control that population. Here in OK, farmers lose 10's of thousands of dollars a year to hogs because of damage to crops/croplands.

Ruger looks, again, to have done a good job on this rifle. It should be very popular, along with the M&P 7.62 model.

To compare piston gun to piston gun, also take a look at the SIG 716. I went with the SIG as I found a good deal on one.

I am satisfied with my Ruger SR556 but it was a bear to get their flash hider off to replace it with a standard A2 to mount my Halo can. I replaced the SIG flash hider with a Gemtech HVT QD mount with no trouble.

December 18, 2013, 03:06 PM
LebbenB: I have heard a lot of good things about the trigger you suggested. I just wanna see what the OEM trigger is capable of right now, and the rifle is still new, so want to keep it all OEM just in case it needs to be sent back to Ruger.

Edit: Thanks again for pointing me towards Harsh Products. I like their Cerekote pattern that I posted a pic of in post #23........ and have a Springfield Armory XD service along with a 10-22 that will most likely get painted up using that same pattern. (It also gives me some ideas regarding a few M14 types I'm quite fond of.)

hrvatska1: Hogs are fairly thick where I'm from, and hunt them year around here. Even the cheap 7.62x51mm FMJ put um in the dirt ifn's I do my part. Once I'm retired, my intent is to hunt them more than I do at present time. As LebbenB mentioned, they breed faster than they can be eradicated, so I'll have my work cut out for me.....lol


Wally: I did compare the RugerSR762 to the Sig 716. Both are very close, and it was a close decision.
After firing a buddies Sig716 the Ruger felt it had a tad less felt recoil and muzzle rise, but they were so close that another individual may feel the opposite as I in this regard.

For me, it came down to the little (personal pref) things...

I really liked how the houge grip felt via the SR762.

I don't need a lot of rail space at the 3/6/9 0'clock positions, and the Ruger hg felt a bit better in my mitts. It also doesn't leave the gas block as exposed compared to the Sig.

The Ruger sold with 3 mags, the case, front sight adjustment tool, 2 sections of rail, and 3 covers.

Around my neck of the woods, most want 200 bucks more for the Sig as compared to the Ruger.

Sig listed weight = 9.3 lbs. Ruger listed weight = 8.6lbs

Nothing against Sig however, and the 716 may prove to be the better rifle in the long run. Folks that need more rail space should defiantly consider the 716.

We will have to compare notes on both of our rifles and see how they pan out for us.

Being a lefty, the Sig's ambi bolt release was very close in winning me over.

If for any reason, the SR762 doesn't meet my expectations, I'll probably either sell it and pick up a Sig 716 patrol, or use the funds to build my LRB M25 that I have put on hold for over 3 years now.....lol

Around my neck of the woods, most want 200 bucks more for the Sig as compared to the Ruger.

That is why I jumped on the SIG when the deal came up -- cheaper than I'd been able to find the Ruger, and $100 below the best SIG 716 price found by the gunwatcher site setup by a member here.

My 716 came with rail covers, good thing as I'm not really a fan of rails, I basically only want a section on the bottom for a bipod or occasionally a vertical grip. I had plenty of spare mags already.

I would recommend Bobro for the mount. They are a little on the pricey side but they are great. Their locking mechanism is a great design. I would say Larue would be a close second but from now on I'm getting Bobro mounts.

Geissele makes a great trigger. I want a Geissele trigger in any gun that I have that they make one for. Easily my favorite.

i've been eyeing this ruger more and more. ruger recently released their new catalog additions and i was hoping to see a new variant. an 18" stainless bbl with an a2 stock similar to their 556 varmint set-up would be nice.

So bottom line, the Ruger does have a fairly high price. Is it worth it?

haven't shot one but i would think that is subjective anyhow. as for price i find it to be fairly competitive, and considering it uses pmags and and has some of the best customer service in the industry, i would have no problem paying the $1700 street price i've been seeing.

$1700. Whoa. I think I must have been thinking expensive 1911's or something....I was thinking $2300 for some weird reason. Well odd as it may seem, that's great news!

1700 and some change is what mine cost.

So far it's been reliable with 160rds down the tube so far.

Felt recoil and muzzle rise are very mild compared to the various other 308 semi's that I have fired in the past. This morning, I dumped a mag into a paper plate at 25 yards, and it was not difficult at all......considering the rifle has a flash hider instead of a muzzle brake.

An 18in bbl version does sound interesting, to include an A2 stock.
The combination might bump up the overall weight of the rifle however.

Going from a 16" barrel to an 18" barrel will add weight with no substantial gain in performance.

I've owned piston ARs since 2006 and I think they're a viable variation to the AR. A couple of maintenance TTPs for gas piston ARs:

Don't let solvents or lube get into the gas system. When cleaning the barrel, keep the piston system facing the sky to prevent solvent/lube from leaking into it from the gas port.

Keep the gas piston, gas block and gas plug dry. If it needs to be cleaned, a scotch guard green scrub pad works well for that job. The piston sleeve should be cleaned by running a dry patch/rag through it.

After several thousand rounds, if the rifle starts to run sluggish, check the gas plug and clear away any carbon build up on the gas ports of the gas plug.

Regularly check the receiver extension for excessive wear near the buffer detent.

Piston ARs don't dump excess gas and carbon into the receiver, true. And most piston AR BCGs will come with a chrome or NiB coating making them feel slick to the touch. A GAS PISTON AR STILL REQUIRES LUBE, just not as much as an expanding gas system AR.

Since there is no standard for gas piston ARs in the same way that there is for DI ARs, see what proprietary parts are available for purchase from the manufacturer.

Resist the urge to over-clean.

The lube combines with the carbon and forms a hard "crust" when it cools. In excessive amounts, it can hang up the gun and it's a PIA to clean out. Look at the tail of the bolt on a DI AR. That's the sort of crust I'm referring to.

I figured it would "coke" with the wrong oil - sounds like it happens fast.

It's not a fast process by any means, unless you give the gas system a healthy squirt of lube prior to putting several hundred rounds down range, LOL. But it can build up over time.

HK states right in the manual to lube the piston, so the above advice is not universally accurate for piston driven rifles. Read the manual and follow the lube guidelines.

I lube all of my pistons and have never had an issue.

My SR762s arrived today. Only took 6 weeks to get them directly from the factory (long story). They are apparently very popular and are backlogged. One of them is actually for someone else but I hope to get out and shoot mine after Christmas.

Interestingly, both came with a note that says they shipped them with metal mags instead of the plastic Magpul mags. They said they found they work better. Both sets of mags with mine say DPMS on them.

I didn't realize that Leupold made a one piece mount for this type of rifle.

Thanks for the info.

How does it shoot now since you have replaced the trigger?

That 762 ruger is very nice. Congrats I wonder from a design and economical standpoint why did they chrome the carrier on a piston gun which runs cleaner in the first place?

According to what I read, Ruger wanted it to be as reliable as possible for a piston gas system in an AR type rifle. If anything, I feel that I over lubed the BCG. ( Old habits.)

The only part that catches any gunk from firing is the piston, which is also chrome....... along with the entire BCM/ bolt assembly, chamber and bbl.

So far, the rifle has proven to be reliable.....and had it out in the snow/ice last night hog hunting.

A friend of mine went with me, and he took along my M14S, which has never failed in wet/ice/snow/mud/dust/dirt.....etc

No issues with the SR762.

We didnt find any hogs last night, and when we got back by late morning, we
I ended up using all 3 mags for some target shooting, and all 3 fed fine.

This rifle will produce 5 shot groups at inside of 1.5 inches at 100 yards, using Win. USA Q3130, and I think it will do better with a decent optic, and match ammo.

The more I shoot it, the more I'm liking it.

Just an FYI,

Was thinking about how to mount a sling on my SR762. The obvious way is to mount the included rail and then buy a swivel or stud that mounts on the rail. I ordered one but while waiting for it I found that a basic sling stud of the machine screw type will screw right into the holes on the bottom/side of the hand guard. Might have to trim it for length and/or use a spacer, lock washer, nut and Loctite but it will work. A couple of them will allow the use of a sling and bi-pod and you could mount the sling on the side as well.

fragout
December 26, 2013, 08:13 PM
Interesting idea Mac66.

I was thinking along similar lines IOT utilize the sling as a shooting aid, but for now, mine is mounted thru the upper slot of the stock, so I can carry it similar to how I run an issued M4 at work.

Here is what I'm using for a front sling swivel, and it's mounted on the upper rail...........

http://vikingtactics.com/slingacc_lpsm.html

It's easy to install, doesn't weigh much, and keeps the rifle where I want a 16inch bbl AR style rifle to be. (It hangs well like this, and vertical to the body.)

Finally got around to using the third mag that the rifle sold with. Works as well as the other 2 so far.

Are you using any of the 3 hand guard grips that came with it yet? I prefer the handguard without anything added to it so far, and probably wont ever use the 2 sections of rail.

mac66
December 27, 2013, 10:02 AM
I don't think anything is lighter or easier than simply screwing a stud into the handguard. You could use them anywhere. The front one has been shortened, the rear one, not yet. Thinking of putting it on the side however.

I've not used the covers or rails yet, I too like the metal handguards the way they are.

December 27, 2013, 03:37 PM
Thanks for the pics.

That does look to be a very simple and lightweight solution.;)

Just to clarify........ The swivel stud that you shortened....... Is it held in place with a lock washer and nut?

mac66
December 27, 2013, 04:19 PM
The front one is held in place with a crush washer and loctite since is screws into the thickest part of the aluminum hand guard and there is no room under the hand guard. The one behind it has some space to add a nut between the hand guard and the barrel. I will likely use the front one for a bi-pod and the rear for a sling in which case i will use a nut on it.

The swivels both lined up well with the rifle.

What optics and rings are you running on yours?

I took my Mueller Speed shot with Burris PEPR mount off one of my AR15s and put it on the SR762. I just needed something to sight the rifle in with. Not sure what I will end up with on it. The Speed Shot is a 1-4x variable. It has a 4 moa black dot reticule that can also be illuminated. Pretty fast at low power at close range. I used it to shoot out to 400 meters with my ARs and it does well.

Updated to add.
I received the swivel stud attachment that fits on the rail. I weighs 2.7 ozs. The stud that screws into the hand guard weighs .17 oz. Big difference in weight particularly when you also add the rail.

I have since moved on of the studs to the side of the hand guard. That will be used for the sling. The one on the bottom will be used for the bi-pod when I use one. I have also since swapped out the stock for a Blackhawk one. The BH has a QD button swivel on the side as well as swivel studs on the side and bottom. A bit nicer stock than the one on the Ruger.

Is this the stock you went with?

http://www.blackhawk.com/product/ADJUSTABLE-ARM4-BUTTSTOCK,1821,166.htm

How does the BH compare to the Ruger stock in terms of weight? From the looks of it, the BH would appear to be the lighter stock. Does it fit well? Any slop compared to the Ruger stock? Any noticeable difference pertaining to overall balance? Other?

I like your sling swivel up front, and may give it a try.
Great ideas you have, and thanks for sharing them. ( BTW.... are you right, or left handed?)

Any other changes planned for your SR?

Saw one for the first time Saturday at my LGS at what looked like a good price. I was pretty tempted but knew nothing about them other than the salesman saying they are relatively new and they can't keep them in stock so didn't want to take a chance. Now it looks like I need to swing by there tomorrow and see if it's still on the wall....

Same here Wally. I got my Sig for $1700 out the door and it comes with a better stock and built in QD button swivels.

A trigger upgrade is all I'm looking at.

That's the stock I went with, primariiy because I bought a couple of them from PSA last summer and they came with the buffer/tube/spring and stock for about $39. I was going to upgrade a couple old AR15 with them. If you've ever priced the push button QD swivels you know they are about $15 each by themselves, so a buffer/tube/spring/stock with a QD stud and push button swivel was as good deal.

Since I had them anyway they slipped right on. No noticeable difference in weight/balance. I'll weigh them just to see. I am right handed and have no further plans for my SR762 presently though I might have to do something about the trigger.
