Thanks for all of the input. I ordered two new 17 round Alexander arms mags(I will need them anyway)to see if it is a mag issue. I will get to the range sometime next week to adjust the gas block and check to see where the bolt is when it hangs up. My lower is a Rock River from a 24in varmint, rifle length. I measured my reloads and they are all in spec as far as I can tell. I will update after my next range trip. Thanks All!
