Robarms XCR FAQ post

hey just got mine in the mail from wanstalls. i have shot about 200 rounds through it now. I am wondering what sort of accuracy people have been getting at 100 yards in .223

Largely dependent upon ammo, IME. With worked-up reloads, you can get 1-2". With bulk American Eagle, ~4.

with sh*tty Chinese surplus, 3-5" groups
I had some reloads out last night, factors were not conducive to accuracy, but obtained roughly 2 inch groups with reloads.

my mistake with my reloads was seating the bullets too long, partially resulting in horizontal stringing.

60 gr noslers
24.5 gr of imr4064
cci lg rifle primers
win brass

if anyone wants the data.
 
awesome thanks the the input. i'll have to cook up some reloads now

not a problem, I'm finding that it's well worth the time!

question for you guys using the fast stock, does it add much weight or does it balance everything out nice?

also, anyone know if wolverine can get the "mini" or "micro" upper (without barrel/tube/etc)
I don't need all the railestate, one guy on arf.com has done it and it's ###y.
 
got another question. anyone else have a problem with some mags not sticking in the magwell primarily the magpul pmags. just wondering if there is a fix for this or should i just contact robinson arms.

No that's not a RA problem.

I find any mags will be difficult to seat when the bolt is forward. If you hold the bolt open, the mags will seat much more easily. With it forward, you have to slam the heck of them in there.

Tap and rack...learn it :)

not RA problem
canada problem
did you buy the pmags from questar?
check the pinning method.
4/6 of my pmags don't drop free.

with bolt closed give the mag a solid tap.

its not that mine wont drop free they wont catch in the magwell. i tried to smack it so it would catch but it wont. the only mags that work are a 20 round one i got with my ar and the ten round one i got with the gun. The magpul mags were from questar. does it not work with thirty round mags or something cause those are the only ones that dont work lol.

the thirty rounders hang up/won't drop free.
so what you are saying is that your pmags won't make it far enough into your magwell to latch in? But two other mags will?

try removing your upper, and seeing where the problem lies with the pmags. pictures will help us.

Here's what my 6.8 was getting at 100 with a 5 round group 2 years ago. I'm under an inch now that she has about 500 rounds through her. I'd shoot more, but 6.8 was too expensive.... But now I've finally set myself up for reloading and I just prepped 225 once fired 6.8 brass, plus picked up 100 new on sale. Life's gonna be good :)

Anyway, I was so happy with my "L" an "M" came home recently. I was lucky enough to find one hanging on a wall in Saskatoon.

As an aside, anyone know where to find some SR-25/AR-10 5 round mags? Marstar has 20's but that's all I can find.

In my experience it is not the mag or the gun, it is the pin head where they pinned it to 5 rounds. If you file it down a little, it should drop free.
