So got the rifle out today, ended up experiencing 4 failure to fire..all of the primers had light indentations

2 on silver bear 62gr, one on Aguila 55gr, one PMC 55g

different mags, is this what i get for buying cheap ammo?

I'm running a BCM 16" M4 upper, and BCM BCG, I've checked out the hammer spring, it's situated behind the hammer, so it "carries" the hammer

Any ideas?

I could be wrong but with the silver bear, they may use a little tougher primers....I know they do in 7.62x39

 

I wonder if they are WOLF. Those things are HARD.

Thanks for the feedback, I'm gonna double check and make sure the pin isnt all goobered up too
