I saw one of these at the last local gunshow. I really liked the looks and it seemed to balance much better than the base model SIG 556, which was very front heavy.

I was amazed how much of a difference half a pound of weight up front made in handling.

However, I did notice that the SIG 551 handguard that was put on the SIG 556 had a noticeable play. In other words, it was not put on tightly. I understand this is due to the difference in SIG 551 and SIG 556 receiver shapes.

Does the gap/play affect the performance of the rifle in any way? If this is not a problem, I think I would purchase one at the next gunshow.

Also, if not SIG 556, what EBR should I buy? I would like to be lazy so AR-15 platform is out (I would spend hours cleaning obsessively). I have an AK clone already and I don't like the ergonomics.

Mircrotech STG556, maybe? A piston-driven AR?
 
I don't like the way the Sig Swat handles, wayy to front heavy.

Well there are certainly a lot of choices out there these days. If you got that kind of dough than perhaps you might want to wait out for the Bushmaster ACR or FN SCAR.

If I were you though, I would get the Kel-Tec RFB or a DSA Tactical Carbine.
 
Where would get the RFB????

That would be the Kel Tec RFB that you bought where???

Been "coming soon" for a while.

Go big, how 'bout a SOCOM 16?
 
Not the SIG 556 SWAT (with that ghastly-looking flashlight/foregrip). The Commando Carbine (supposedly a limited edition of 1,000) that has green SIG 551 furniture.

Not really. You can shim it up somewhat using aluminum tape and velcro, but it doesn't really affect anything.

There's a *WORLD* of difference in handling between a Commando and a SWAT.

I would suggest the Robinson Arms XCR

I have one and it runs great I am kinda like you I do not like to clean but I do it every once in a while it has been atleast 700-800 rounds of wolf and silver bear since I cleaned it last and the only mafunction has been a double feed caused by a bad magazine follower. The accuracy is good. It is a little more front heavy then a DI AR but that is beacause of the piston system. I would highly recommend it to anyone.

If you have any questions let me know and I will try to answer them
 
I have an MSAR STG-556 w/over a thousand rds through it so far. Liked it so much that I've got a 2nd on the way. The short OAL makes it very quick & manueverable, especially in tight quarters. The weight is closer-in to the body so there's less shooter fatigue. Breaks down quickly/easily and cleaning is a snap compared to AR's. Mags are proprietary & pricey compared to AR mags but are extremely rugged & well-built. Adjustable gas system is very nice but the STG has a typical bullpup trigger so it will never be as nice as an AR's trigger (still great for CQB but not suited for precision work). My biggest complaints about the STG are the trigger (you can get a Trigger Tamer for it if you wish), the front QD sling swivel position is too close to the charging handle for my tastes (YMMV) and mounted optics need to avoid protrusions on the left so as to avoid snagging fingers when working the charging handle.

Here's my STG-556 w/Trijicon RX30 Reflex sight, LaserMax laser just forward of the RX30, TLR-1 taclight w/remote tapeswitch & GearSector ASP single point sling adapter:

I've read some horror stories of both Robinson Arms XCR and MSAR STG-556, so I am wary (although MSAR seems to have an excellent reputation for customer service).
 
I don't know how reliable these stories are and I do not remember the specifics, but some gun boards had disgruntled reviews by customers of Robinson Arms.

Ehhh. Some gun boards have disgruntled reviews of dihydrogen monoxide.

You *could* die from ingesting too much dihydrogen monoxide. In fact, I believe more children die each year from accidents involving dihyrogen monoxide in 10 gallon buckets than from guns.

In all seriousness, while I doubt the scientific reliability of these sorts of internet rumor mongering/disgruntled gun owner reviews, one has to find a proxy for overall reliability and customer service, and when one brand experiences more online agony than another brand, there might be something to that "smoke," no?
 
BTW, how is the quality of the factory mounted 1.5x optic on the MSAR STG-556?

From what I've heard/read quality is good but it's non-illuminated and the 1.5x magnification isn't really enough to help for distance work but is enough to interfere w/CQB-style shooting. HTH...

Wasn't the whole point of a 1.5x magnification that it offered something greater than 1x, but still allowed both-eyes-open shooting for close quarters shooting?

Yes, but remember that particular optic & concept are over 30yrs old and are best illustrated currently w/the ACOG's Biden sighting concept (which is easier for some to master than others). Unfortunately the 1.5x doesn't have the magnification or FOV of the ACOG.

In the end, I ordered the SIG 556 Commando Carbine. I seriously considered XCR and STG556, but what decided the matter for me was my previous customer service experience with SIG, which was outstanding.
 
There seems to be all this drama about Robinson Arms on the internet. What is that all about?
 
Not too wild about Robinson Arms stuff.

Not after all of the promises revolving around the M96 from what, 10 years ago, and still being floated. Recalls and such don't add to any sort of confidence in them.
 
Just curious what horror stories have you heard about the XCR ? I know of only a few issues that people have had and every time RA Customer Service has taken care of it

As I read through this:

http://xcrforum.com/index.php?PHPSES...7dd&board=30.0

I get the feeling it's more than just a "few" issues. Anytime I read "Stickys" on how to deal with issues, I tend to take notice.

Have you had any problems with yours?

Chuck

I see those posts as helpful that away future buyers and current owners know what to look for. I think that the number of issues are actualy low for as new of a weapons system, I look at the issues the M16 had in the begging and the number of issues the XCR has is low in comparison.

However I have had a few issues with my XCR but I caused most of them

First one I had I broke the disconnector when I was taking the trigger assembly apart, but RA took care of me and sent me a new disconnector and disconnector spring and only charged me shipping.

Second issue my Ejector came loose but I did not had not completed the suggested maintenance but do the thread on the xcrforum it was an easy issue to fix, I say this is as much my fault as Robinson Arms.

Third issue, I was unable to remove my barrel I tried to remove my barrel one day to clean it but I was unable to but this is why the last time that I took it apart to clean it I did not put it together right I did not pay attention to barrel when I put it back in the Upper so when I put the barrel locking screw in place I locked the barrel in place also because I did not have the barrel in all the way, so when I tried to fix it I put the upper in a vice with a cloth around to so that I did not damage it while I tried to pull the barrel out but I ended up putting the vise to tight and I damaged the upper and the gas tube, so I sent it back to Robinson Arms to have the barrel removed and the upper fixed they took care of it by getting the barrel removed and replacing the upper and gas tube at the same time I decided to get a heavy barrel instead of the light they fixed everything and only charged me shipping and cost of parts. I claim full responsibility for this Robinson Arms had no power over this happening and yet they still took care of me ( talk about customer service )

Fourth Issue- Was a broken Firing Pin or debris being in the firing pin hole this just happened the last time I was at the range the rifle would not fire I checked the primers and they were not being struck and since it was dark out I was not able to see to fix it at that time I checked it the next day and found out that it was caused by either a broken firing pin or debris being in the firing pin hole I attempted to remove the firing pin using Robinson Arms instructions but was not able to I also tried to flush any debris out with breakfree but nothing came out so I sent it back to Robinson Arms on Friday to be fixed and I still do not know what caused it to happen. This happened after about 1200-1500 rounds of Wolf and Silver Bear without any cleaning or oiling and after being knocked around in a Jeep Wrangler after 4 wheeling for a weekend on extremly rocky trails and very step inclines and declines. I can not say for sure who was at fault.

Overall I have had 4 Issues and 2 of the 4 are completly my fault and one of the others are partially my fault and the other might be partially my fault. Throughout all of this Robinson Arms has taken care of me they have the best customer service of any company I have ever dealt with
 
Get the SIG. It is reliable, and most of the worst bugs have been worked out of it, as I understand it.

In all seriousness, while I doubt the scientific reliability of these sorts of INTERNET rumor mongering/disgruntled gun owner reviews, one has to find a proxy for overall reliability and customer service, and when one brand experiences more on-line agony than another brand, there might be something to that "smoke," no?

Ah, the ole' sticky standard. I don't know of any weapon sold that doesn't have some stickies posted somewhere on the INTERNET.

The biggest complaint I have heard against Robinson Arms, is they don’t deliver their promised new stuff on time. Never heard that in this industry before. Ask about the Magpul Mazada or this week it is called the BushMaster ACR, or……. I can’t buy it yet, but a lot of folks tell me what a great carbine it is, and they are going to get one as soon as they are available. WHY? VAPORWARE!

Other companies refuse to sell a semi Auto version of their carbine to me. Hell yes, as soon as I can, I want to do business with them. My kind of people, no doubt.

Or any of the HK models and or variants, try to use the phrase, "good customer service" and HK in the same sentence. No one living or dead has seen or heard of good service from HK.

SIG, I think the top rails are now being put on straight, and the hand guards that should have originally been on the rifle will be available ‘real soon‘ now. Should be a pretty good rifle once they get it together. ???. I know several folks happy with theirs.

AR variants, I understand some are better than others. I hope so after almost 50 years of trying. I am told COLT is the only one that is truly MILSPEC (I understand, they go for about 1300+/- before rails and other necessary attachments). And of course FN, but as stated above, they will not sell me one.

Many folks here have a much higher standard from the companies they deal with. My standard is pretty low. If it gets the people using it dead, I don’t want one. Where as most of the folks here will take one of those, and not buy from an outfit that they heard rumors about not having good customer service, maybe. No doubt I have much lower standards. But inspite of that, some folks are happy with theirs.

I will not buy/use an AR style weapon because friends of mine were killed and wounded because of the POS. I bagged and tagged the dead ones, and MedEvaced the wounded.

Here we are 40 years later, for me, and American troops are still being killed and captured because of the same POS. I will stop my rant right here. I have plenty more. You know, not INTERNET stuff, documented stuff, but that doesn’t seem to impress anyone.

Look, if you don't like something, fine, this is America, you don't need an excuse. Particularly a ginned up one. Are there features you might like or not like, of course. The forward weight is some of these new carbines, will help when tracking a moving target (look under shotguns). You may or may not need that.


But you folks with the higher standards are no doubt much smarter and a lot more experienced than I am. I just try to apply the same standards to everyones products, not just the one’s I am wanting or have or like. Just another stupid old guy.

Sheesh….

Go figure.

I ordered the SIG 556 Commando Carbine, and it should arrive in a couple of days.

So, now, I ought to purchase some magazines. How about Magpul PMAGs? The ones with little windows? I hear lots of people like them.

Are PMAGs also good in 20 round versions?

What about Lancer (completely transparent) mags? Since I am going for the whole SIG 551 look, shouldn't I get some completely transparent mags as well? Only if they are reliable, of course.
