Mine has only had 1 set of problems, the mags needed to be broken in(which they didn't ell me). I broke them in by loading them to 75% capacity(15 rds.). After about 100 rounds they are flawless. The spring was just too strong at first. Now mine will eat anything its fed, from match to crap from portugal to handloads, if its 308/7.62x51 it will load and fire it!!
I had a AR10 and that was a headache, this is the best 308 I own/owned.
Questions please feel free to IM me.
