| I have a LMT SBR with a AAC M42K suppressor that runs about 90 rds through before I start to get FTF's. I'll hit the bolt release and the bolt will not chamber a round, it will barely move. I've been shooting AE .223 55 gr. ammo through it. I'm thinking the ammo isn't "hot" enough for it. Any suggestions ? |
