Failure to feed problems.
1 out of 10 rounds fail to feed. Went through 300 rounds of American eagle mixed with walmarts UMC FMJ.
Gun is fairly new approx. 600 rds total.
I'm thinking it maybe the magizines with stiff springs. Loading the 10th round is pretty hard compared to loading the first.
But then I think about those fortunate enough to use 17 rd mags.
No signs of limp wristing.
What else could it be?
