Cr, I apologize, I shouldn't have made it personal. I should have stayed factual, so here goes.
AR vs XCR, all comes down to it's status. Do you want to shoot in the bush?
There are better range guns than the XCR. Perhaps an ACR in 300blk.
I've never owned an AR, so I won't comment other than 1 match I was in.
2 XCR, 1 Tavor, 1 SA, 20 ARs. 4 guns broke down, all ARs. Various problems.
I havent formed an opinion of ARs based on that, if ARs were nr, I'd have one.
When I bought my XCR, it was so I could shoot in the bush. It's never seen a range.
I've run 12000+ rounds of Russians finest, all corrosive. Nothing but the best for my girl. I'm the guy who replaced numerous parts, which were an op-rod, and firing pin spring. The op-rod may be common, as it was upgraded. The broken spring was a small section of the end coil. Doesn't matter, shouldn't have broke. The rod was at 3800, the spring I don't recall atm.
I've recently broken the hammer spring. The cause was bump firing, 6 mags. I'm not proud of that

. That was ~160 rounds ago, it still cycles and fires 95%.
I've had the rifle lock up once, it was a gooder. I field stripped it, oiled 'er up and kept on going. It bent a case while feeding. The rifle was glowing at this point, I was afraid it was going to cook the unfired round.
With over 12000 rounds, should I expect more?
Before you answer that, you need to know the abuse my rifle has been through. I'm not a range shooter, I set up courses with up to 100 targets over 100 yard run. I can't so that at the range. I shoot it hard, I have 14 mags for a reason. I treat it like a rental. I've got al least an hour of video if anyone's in question.
I'm pretty sure I can break just about any rifle. C'mon caramel, send me your fancy rig. I'll do some real testing for you. I'll need ammo too please.
If you want to shoot tiny groups from the bench, the XCR is not your gun.
If you'll be at the range 100%, the XCR is not your gun.
For a nr, do-all well but nothing perfect, black rifle, I've been impressed with my XCR.
