XCR Reliability in 7.6x39

Hey guys,

I've been considering an XCR in 7.62x39 for some time now, but was wondering what the consensus is on feeding reliability? I've got a number of 7.62x39 AR mags that feed reasonable well in my PWS with the occasional hiccup with a round nosediving into the front of the magazine (~every 200-300 rounds).

I would imagine similar issues would be present with XCR because they use the same magazine, but does anyone have experience with both?

Thanks for the feedback!

I use XCR 10 rounders and I suppose its same as the LAR. No issues with the mags.

What he said. I run 16 XCR pistol magazines and only had 3 failures to feed when my rifle was brand new, Im around 2000 deep so far and runs 100%.

Gas block set to position 2 and I just fire away till it gets too hot to hold comfortably.
 
When you buy it, make sure it has the correct brass deflector for 7.62x39. If it has the 223 one, the empty casings will periodically eject back into the chamber. Both my buddy's rifle and mine were shipped with the wrong deflector but was corrected shortly after by the dealer.

Oh yes... and they're super reliable. My buddy shot a moose with his this season :D
 
I have the factory 10 round mags for .223 from rob arm. What I have noticed is that I can't fill them up past 5 rounds or I risk damaging ammunition. ...so...kinda disappointing. I don't know if I got a batch with slightly stronger follower springs or what. But what happens when I fill it is after I fire the first round, it grabs the second round just fine but the friction between the second and third round shoves the third round forward with considerable force. The damage that occurs to the ammunition is the bullet gets push into the casing a considerable distance and if I am using balistic tipped ammo the tip is destroyed. Not cool.

Try loading the mags and leaving them loaded for a couple of weeks, the spring should take a set (shorten) - also, never use uncrimped rounds in a semi, the RA was designed for military ball ammo.

X2 they love surplus ammunition, chugs along all day and you gotta love that stink.
 
I have a couple mags that work more reliably with 9 rounds instead of 10. Of course that might just be my gun...
The X39 has run like a champ. I'm not a keep count of rounds guys but I'm going to say it's over 3000 rounds of Czech surplus. I had to replace the ejector spring on mine this year. The "spring" is actually a little rubber cylinder that had lost it's squish resistance (technical term). I attributed that to my hot water cleaning regime and oil bath after each range trip. Not a spec of rust anywhere.

Yeah I get that. ...but I use mine for yotes. So I'm using commercial ammo. ...which is fine when I load less. And its not very practical to only use military ball.
 
That's funny stuff, Steiner. Feeding my ego ;)
I don't know how I missed this thread, I love me some x39 XCR.

Op, did you buy the gun?

In my limited experience, any or all feed issues will be mag related. The XCR was "inspired by the AK", (Mr R said it so don't bash me).
It's a loose gun. You could throw a round from 3 feet, it'll find its way in the chamber.

Some mags, or maybe 20 of mine, needed tweaking. The top round doesn't sit high enough. The feed lips at the rear, primer end where they roll around the case, are too close together. I spread them until half the primer is visible. I slide a wrench over them(individually) and pry them outward.

Full mags, (cough)5 or 10 rounds should load on a closed bolt in any gun. If they don't, it's the mag not the gun. I use ranger plate and had to trim the follower legs for every mag. I can load on a closed bolt with any mag and don't feel the follower bottoming out. I can't load 11 rounds.

I'm still this side of 20,000 rounds, but close. I've never had a feed issue that wasn't mag related, or user error by way of running on gas 1, too soon. That was my first day with the rifle, seeing what does what. I highly recommend experimenting with the rifle, inducing failures, use every gas setting, shut the gas off run as a straight pull bolt, remove the gas valve, etc. See what does what and learn the rifle, as with any gun. Figure it out on your terms, so your not stuck with #### in hand wondering what to do. :)

If we had full mag capacity, 30 rounds would have to be fed through a banana. That's where any myth started about feed reliability.

Anyways, did you buy the gun?

Edit for clarification;
When I say I don't feel the follower bottoming, I mean; when I load a full mag to a closed bolt, there's no interference from the follower legs as I'm loading. I feel the spring compressing but they still load freely. No force required.
