I desperately want a functional 7.62 upper, which is consuming an enormous amount of time and money to no avail. Someone talk me out of this madness and help me help myself. Like Homer Simpson says, "if the government won't stop me from eating too much, who will?" I've tried a DPMS and an Oly Arms, 4 mags from various manufacturers, on my 5 lowers and none of them work with anything reliably, and they won't shoot hard primers at all, even with the MGI Bolt and Firing Pin, my rig fires 1 out of 25 wolfs. To be fair, it fired 0 out of 25 before. Will someone please talk me back from the edge of this insanity?
