RA XCR-L light barrel accuracy issues????
- Thread starter kykamo
- Start date
From a functional accuracy standpoint, my light barrel 7.62x39 XCR is fine. It will put it on an 10x10 steel at 300 meters with boring regularity. I'm sure it would do it to 400 as well, but 400 meter ranges are thin on the ground in this neck of the woods. I wouldn't worry about the accuracy as long as you're not looking for sub moa accuracy.
You really have to take accuracy reports with a grain of salt.
It's so common to see guys like a certain rifle because it shoots to their standards with their predetermined choice of ammo. This is a key distinction...
Do you buy a rifle to suit your ammo or buy (or hand load) ammo to suit your rifle?
Case in point... I have a Bushmaster ACR DMR that started out shooting 4.5 inch groups at 100 yards.. I was not a happy camper. That was with 69 grain SMKs which should have shot faily well In that rifle... (1:7 barrel twist rate)
Well I fiddled with it and got it to shoot 2 inch groups with 69 grain SMKs....
Then the 77 grain bullets I ordered finally arrived and now its shooting under 0.75 inches at 100 yards. No big surprize here because 1:7 twist barrels are suitable for heavy bullets.
Now you have to ask yourself when someone provides accuracy feedback ... how much effort went into optimizing the match between rifle and ammo before drawing a conclusion.
Sorry, this might not help answer your question, but hopefully it provides some insights to help you read between the lines and assess the credibility of accuracy reports.

Good choices worst case you can always drop it in the EE

Good post
I can get my XCR-L pencil barrel to group Hornady Superformance 75 grain consistently @ <1.5moa. Even got a 5 shot group sub MOA. This is with an ACOG 4x32 supported off the magazine...and I'm not a terribly patient nor talented shooter. lol With spam can Norinco 5.56 it opens up to around 3".
The pencil barrel heats up quick, but also cools very quickly.

Whoever said that was full of $hit. Just the usual gun store gossip crap that the sales people spill out even though they have no experience with the XCR line. I have experienced this first hand over and over again with different "sales" people.
The groups will open up after 5-10 rounds ever so slightly, then gradually get bigger as the barrel gets hotter. The newer XCR line is capable of Sub-MOA accuracy, I have done it, seen it, and know it with both heavy and light profile barrels, and multiple calibers (mostly 5.56 and 7.62x51).
In the discussion of accuracy, 98% or more of the time, accuracy problems are shooter error, period. People just don't want to admit they are at fault and blame the firearm. I get every tom #### and harry in the range claiming the guns "sights are off" or the "barrel is shot out" and I get it so often I now walk to the ammo cabinet, grab 5 rounds and put them in an inch group just to show them they are wrong because they will not hear it, they have to be shown it. Too much testosterone these days
Just my .02 on these accuracy threads. They get quite old after a while.

Thanks a lot driller212, very informative. I'll get the light barrel and not look back.
One thing I'd like to ask about is when you said the XCR "newer line." Which ones are those? Are they the keymod ones, a certain year of production or serial number?
'll also ask here if any of the xcr's come with the Omni brass deflector, fast2 stock and type 2 parts? Or do you have to buy those "upgraded" parts?
Thanks for your help guys, I appreciate it

The first generation of XCR-L rifles were a slightly different design and had some minor teething issues. The buffers were prone to damage if the firearm was over gassed, and the piston tubes were a little loose and that affected harmonics and accuracy. They also had a rubber buffer pad at the rear of the receiver that was meant to be replaced every now and again, and the bolt catch would wear prematurely due to poor heat treating. The newer gen includes both picatinny railed and keymod versions, however the keymod versions are the tightest, lightest, and the most accurate. That being said, I would be surprised if most people on here could shoot the rifle to its true potential.
All of the current XCR rifles on the shelves should come with the fast 2 and type 2 (or gen 2) parts from factory. I am unfamiliar with the make of the brass deflector, however.
As long as it's keymod you won't have an issue. I've seen different editions of the FAST stock on keymod and different muzzle devices .. instead of trying to explain it all here, I'll just link you to Robinson Armaments parts page description: https://robinsonarmament.com/xcr-part-identification/ .
I've not seen the omni deflector shipping on full guns yet, but Wolverine Supplies just got them in as parts.
"[FONT="]In the past there was a separate Brass Deflector for each caliber. In some cases, using the wrong brass deflector caused malfunctions. The “Omni” deflector shown on the bottom not only works well with all calibers but often allows the operator to run the firearm at a much lower gas setting resulting in a lower recoil impulse without sacrificing reliability. This is very important improvement and highly recommended for any serious XCR user."[/FONT]

Was shooting my pencil barrel today in the hot sun. Wanted to make some slight adjustments to my zero bcuz i knew it was off. First group 5 shots was decent 3inches @ 100 yards on a plastic table. started doing some quick firing on steel, went back to paper and my groups were so large they wernt even groups anymore. The barrel and handguard were scortching hot but I dunno if it can affect accuracy that badly. Actually considering the scope might not be retaining zero, will need to check next time I get out there.
Has anyone experimented with re-torquing the barrel retention bolt when the rifle is hot?
Metal expands when it heats up which could potentially change the tension of the retention bolt, it you re-torque it when hot it would be at 250 in-lb when you're using it. Not sure it would make a lot of difference but it may be worth experimenting with to see if the consistency improves as it warms up.
