Ive only got about 300 rds through mine but I keep getting bolt feed failures(?). When you hit the bolt release button on the side sometimes it hangs up and you have to pull the charging handle. Cleaned it twice already after each use. Doesn't hang up right away but after a few mags. Recoil cycles fine. Figured it was a break in thing. Hung up 4 times so far. Any ideas?
