I got a brand-new WW-15 (Windham Weaponry AR-15), my first AR, and after getting it sighted in I like it a lot. I find it shoots straight and I haven't had any issues with it except this one.
Out of 300 rounds, 4 or 5 times — always in the middle of a magazine, never right after mag insertion — the bolt would fail to travel all the way forward. It would feed the next round just fine, but stop about an inch back. At that point the trigger pulls and I think "misfire" and drop the mag, keeping the rifle pointed toward the target. Visual inspection shows slightly open bolt and a pristine round in the chamber. Now the forward assist will do nothing and the charging handle will not move the bolt forward or back by pushing or pulling on it. Wait a few seconds and the charging handle pulls the bolt all the way back quite easily. Let it go, it snaps forward like it should and seats right up snug in the battery like it ought to. Then it will finish the mag just fine, maybe another full mag or two, but then the same problem happens.
I've been running it wet, like people say to do, using Ballistol which was recommended to me, and I cleaned it thoroughly after the first firing of 100 rounds. No hang-ups with the first hundred, btw.
I'm wondering: Could the problem be that I've been shooting the steel WPA .223 the shop sold me with the rifle (I didn't think to specify brass, or that I might need to do so). Or does the rifle just need more of a break-in period? Something else, maybe? I'd appreciate any ideas.
