I put about 70 rd through mine today. Bolt release was stiff sometimes, and sometimes not. Got to get used to where that charging handle is, I smacked my hand a couple of times with it. There are still a bunch of peeps not aware of this rifle, everyone that entered the range stopped to take a peek at mine
No problems what so ever with bolt locking back after last round, or FTF or anything. A little brass on the deflector and that is to be expected. So far I love it.
