Hey Guys,

I have an AR15 5.56 and enjoy the fun, but I'm looking to reach out a little more with an AR10 platform. Ultimately here I want a rifle that will produce a minute of angle or better at 100yds and I'd like to keep it under 2k. Looking for guys with experience to way in with options, suggestions, etc. Really appreciate the help fellas.
 
Very happy with my Ruger 762.

Had to change the trigger on it to suit me but fine armament otherwise.

If I wasn't married to the Ruger i'd look at the S&W AR10. Lightest on the market and well thought of as well.
 
I have very limited experience with the AR10 platform...

But I would go with the Ruger SR762 as well. Piston driven, Ruger quality and service, with good features and great value for money.

If you wanted more of a benchrest, long range kinda gun, I have heard good things about the accuracy of Armalite and DPMS AR10 rifles: both come in many different barrel styles and lengths to fit your needs.

If you are looking for maximum accuacy, have you considered the M1A (not meaning to derail)??
 
Some .30-cal ARs cost more, some less, but I didn't want to pay good money for one that was ammo-finicky and hiccup-prone as between 7.62 mil surplus ball and the various .308 commercial ammo. That eliminated S&W's M&P for me. Had no interested in throwing more $$$ at a smith to make it run with both ammo, or in trying to do it myself.

The Ruger 7.62 wasn't out yet, and the LGS wanted well north of $3,000 for a SCAR 17 that takes only expensive proprietary mags, not the less spendy & readily-available SR-25 pattern mags, such as those MagPul makes.

So after looking at the various makes on the market (KAC, DPMS), I decided to go with LMT's LM8, which is the "trimmer" version of their MWS MRP. (The Brits adopted the 7.62 MWS MRP for their troops, which is a good indicator of quality, since the MWS had to beat out several other 7.62 & .308 competitors.)

The MRP system allows for easy barrel-swapping, and although mine came with the 16" C/L tube installed, I picked up an 18" SS barrel (1/11.25 twist) for precision use at longer distances, knowing I would scope it.

So I can run my rifle in 2 modes: as a 16" "tactical blaster" with a RDS, or as a scoped 18" SPR-type precision rig.

Tactical set-up:

Hope this helps.

:cool:

I am much happier with my new psa than I ever was with the ruger. The ruger was heavier, the handguards can not be changed, the gas block makes a good front grip hard because you burn yourself. The chrome bcg was nice but after a few hundred rounds the regulator was a pain to get a part. The ruger is a good reliable rifle but some things could have been done better. Plus for the money difference I can put a nice trijicon scope on the psa.

I have the lower built on my PSA, debating on what to do for the upper while I save up. What upper did you go with, and how is the accuracy?

I am thinking about doing the 18" free-float melonite.
 
Fortunately when I put together my AR10 rifle about 20 years ago the selection was limited, very limited. Today there must be a few dozen companies marketing the AR10 platform. Actually only Armalite owns the AR10 naming rights so everyone has their own name.

Unfortunately unlike the AR15 the AR10 rifles lack standardization.

AR-10 Compatibility Warning:

This notice pertains to any rifle based on the large format AR-10-type or LR-308 platform typically chambered in .308 Winchester, 7.62x51 NATO or other cartridges requiring the longer magazine format. This includes, but is not limited to, the ArmaLite AR-10, Bushmaster BAR-10, Rock River LAR-8, DPMS LR-308, KA SR-25/M110 series, POF P-308 series, Larue Tactical OSR and JP LRP-07™.

Unlike the AR-15/M16 platform, for which most parts are cross compatible due to the receivers’ standardized design, the large format platforms have not been standardized. Before ordering accessories and parts for your large format rifle, make sure the parts are compatible with your particular rifle platform. The only parts that are universally cross compatible are fire control components. Hand guards and barrels are each slightly different and may not be cross compatible.

Hand Guards: In the JP nomenclature for hand guards, the “D” at the end of the part code refers to rifles using the DPMS LR-308 thread pattern on the upper receiver barrel collar. The “A” refers to rifles using the Armalite thread pattern, which includes the Bushmaster BAR-10 or Rock River LAR-8. JP hand guards using the letter “M” are only compatible with the AR-15/M16 platform and will not fit on any AR-10-type rifle.

Barrels: JP Supermatch™ barrels in .308 Winchester/ 7.62x51 or .260 Remington are compatible with most AR-10 platforms except the Rock River LAR-8 or Bushmaster BAR-10. Due to the use of an FAL magazine, the extension piece on the barrels used in those rifles must be extensively modified to allow for feeding. Therefore, JP .308 and .260 barrels are not compatible with the RRA or BM rifles. However, our barrels may be modified to work with the LAR-8 or Bushmaster BAR-10 rifles.

Gas Tubes: The gas tubes used in the ArmaLite rifles is longer than the gas tubes used in all other platforms. Standard gas tubes are not compatible with ArmaLite rifles or in particular, barrels using the ArmaLite port position.

Fire Control Parts: All the large format variants that we are aware of will accept standard AR-15 type fire control components, but the setup may vary significantly between platforms. In the case of JP Fire Control Components, it is essential to use the “red” hammer spring provided with the kit. The hammer spring must be of a higher spring rate to ensure both ignition reliability and resistance to finger bounce-off doubling. Release weight on a .308 caliber self-loaders must be at least 3.5 lbs. or greater. With a lighter release than this, you may experience finger-bounce doubling or the firing of more than one round with each pull of the trigger. This is not acceptable for both safety and legal reasons.

That should give you some idea as to the compatibility of parts. Every forum member who post in this thread will also own the best make and model ever produced. :)

You will need to decide which rifle works best for you, things like stock style and barrel length come to mind. Also, which magazines work in which rifles. Then there is a matter of the rifle's intended application? Punch paper, hunt hogs, defend your property against all enemies foreign and domestic? You get the idea. :)

The S&W M&P 10 was doing real well till folks started having ammunition issues and getting the guns to cycle with a wide variety of ammunition. My read is many finally just enlarged the gas port and things worked.

The Ruger SR762 gets a good rap and most guys that shoot them have no complaints.

Heck, the list just goes on and on depending on what you want. Just be aware of parts comparability between rifles. You want to get it right the first time. You want what works for you and trips your trigger.

I have the 16" melonite with rifle gas system. It cost 630 with the MI hanguard. So far 100% with everything from wolf to cbc to premium 308. I am waiting on a fixed stock that should be in on Monday. After that I'm going to zero the scope the rest of the way. I have a CMC trigger in it but even the factory trigger wasn't terrible. After I get it sighted ill let you know exactly how it does but I'm not a real precision shooter. 2 moa is fine for me. For what the complete upper cost even if you put a rainier match barrel on it and sold the factory barrel you'd still be ahead.
 
My personal ownership experience with AR308s is a POF P308 which is a consistent sub moa rifle but it's over your suggested budget. I have some experience with a friend's LaRue and Knights both of which are easily sub moa rifles but also over your budget. I've shot a number of DPMS AR308s owned by others and have been impressed with the accuracy. Of the three that I've shot they've all been sub moa rifles and one was close to 1/2 moa with factory Remington Premier Match. We're in the golden age of AR308s with so many great choices. I don't need or want another AR308 but if I were looking for one I'd most likely buy a LaRue PredatOBR with a 14.5" barrel to use with my AAC 762 SDN 6 suppressor.

I recently built a PSA lower as well. I am missing the stock, thinking of the PRS.

I will soon be looking into an upper receiver.

Tell me more about your PSA

Accuracy?

Quality?

Reliability?

I bought a PSA 308 lower and kit
 
If I had my choice the knights would be it, but this life wouldn't be normal if we all got we wanted now would it? I'm leaning towards the DPMS LR308. From what I'm gathering you can't beat the prices for the accuracy.
 
Dpms recon is a great gun and a great buy but its gonna depend on what u want to do with the gun which model I would go with.
 
Good point. I'd like to get out to 800yds with this gun tops...but be fairly accurate with it out to that range...
 
.308 ar

i like my rockriver lar8-a4 standard rifle model 20" it is 1" moa at 100yards i like the use of fal metric magazine's l1a1 inch magazine's ,so your not locked into proprietary part's .they have several model's available.
 
blackops: My Son shoots two DPMS 308 cal AR-10`s a long HD barreled rifle and a shorter, sporter barreled rifle. And both of them are extremely accurate but the HD barreled rifle is scarey accurate. Me on the other hand, I have always had very good luck with ArmaLite`s and have a couple of really fine shooters, to me in 5.56 cal. However several years ago a ArmaLite AR-10 ( T ) in 308 cal came my way. It was truely a gift to me, from the Man upstairs. This Rifle is on the other side of being scarey accurate, I shoot this rifle alot, and like it more every time I use it. I am truely very lucky to own it. We both shoot 46.0 grs of Varget and use a 150gr Nosler BT bullet and Win LRP`s, for around 2900 fps. In all three of our AR-10`s and several 308 bolt guns. This load for us shoots well under an inch off of a bench, at a 100yds. In any of the 308 cal rifles we own. You should be able to get a nice AR-10 for around 2K, I would think. Good Luck To You:

blackops - Would you consider building?

You might be able to do a lightweight build for ~$2000 and hand pick all of the parts you want.
 
I'm actually starting to consider slowly building my own piece. I have a lot of research to do if I got that route. Been looking at going with a TWS upper or POF upper to start.

I was looking at a DPMS LR complete for the money, but from what I've gathered it's hit or miss getting a sub moa gun. I don't want to purchase a rifle, then fight to get the gun to hold a moa. I want a gun i know is sub moa from the get go guaranteed. Do any manufactures guarantee a MOA for under 2k?
 
DPMS LR308, 24" H-Bar. Under $1000 if you get a good deal<$1200 if you pay list price. 1/2 MOA with match ammo, or good handloads? All it needs is a new trigger to make it world class. I have two, ( In case one breaks during a match?) trade off every other stage to let them cool. No stopages in almost ten years, inc prairy puppies in Wyoming, Colorado and Utah by the thousands.
