[AR1516]

Hello, I'm new here to this forum. I just have basic question about the gap between the upper and lower receiver on the standard XCR. I was curious what is an acceptable gap between the two? I have a little over a half mm (.58mm). You can easily see light between them when mated. Is this normal?

Pretty much.

Same as an AR15.

But with less wiggle between the upper and lower.

It's about the same as an AR15. You can just barely get a finger nail in there

Thanks for the responses. The fit is tight and I'm too concerned with it, just looks a little wide. I have several AR style rifles from different manufactures and none have that large of a gap, I do have some with a little wiggle though.

I do like the rifle though. I bought it used, unfired, and it happen to be one that was recalled...Terra took care of me, and I couldn't be happier. I have shot just a little over 200 rds through it thus far and it is very accurate and reliable. I have not had a stoppage yet! Looks like I have new favorite gun.

200 rounds isn't going anywhere yet (GRIN)

Typically, a well-lubed and cleaned AR can go a bunch of rounds before it starts having problems.
So I doubled that number, and put that through the XCR without cleaning or lubing.
No problems. Not one.

I'm not talking hundreds of rounds, I'm talking thousands. Did a nifty write-up on it too, years ago when it happened.

Show me ONE AR15 that can tolerate that, and I'll buy it from you at double the price you paid ;D

I hear you there, no AR15 will put as many down range as the XCR. I got back after putting another 300 through the XCR and still working great. I did notice some small brass shards on the extension. I not thinking that it is anything to worry about. Time to give her a cleaning.

Nope, nothing to concern yourself over.

FWIW, there are three carbines / rifles I've got that are "go to" or "never fail" sticks. An AK in 5.56 (WAS 100%, until fedex rolled over it), the M14 sticks, and the XCR sticks.

In all three cases, I've put enough rounds down range that the magwell / bolt area looked like it was glitter-coated from the primer laquer.

Impressive stuff.
