I ran the carbine through two classes so far. total about 1000 rounds. this is right out of the box, light lube and zero with Aimpint T1. so far, not issue what so ever. but again, this is only about 1000 rounds of Winchester white box.

I am impressed withhow light the rifle is, how accurate, and easy of handling.

only issue was during a loading process, I was not exactly in a perfect positon, I applied some downward pressure to the charging handle. the edge of the charging handle hit the bump on the steel stock, i assume the chanrging handle had come to a full stop and let the handle slam forward. the end result was the round was not chambered. once you understand this little glutch, i never had another issue.
