Rifle has around 1,500 rounds on barrel before it was cut to 14 1/2. Never had a problem with rifle shooting M855 ,M193, and Black Hills 77grn. Picked up rifle today after barrel was cut and break was pinned and visited suppressor at dealer, chronographed and sighted in cut barrel with 77grn unsuppressed then suppressed no problems. Shot about 30 rounds. Then switched to Independence 55grn 5.56 and shot about 60 rounds suppressed when I had a malfunction. Had a primer stuck above chambered round which wouldn't let the bolt go into battery. Pulled the BCG out and pried the round out of the chamber and checked things over. No damage. Let suppressor cool off then started to fire same ammo again. About round 15 same thing. Blown primer. It was about 95 degrees out and I wouldn't say I was firing fast but the rifle was somewhat hot. I'm thinking the ammo is the problem as this is the cheapest ammo I've come across. $8.99 a box. I've searched the threads and I'm kind of thinking over presser but I've never had any problems with this rifle before, I did fire about 15 rounds with suppressor off after the second malfunction and rifle ran fine. Should I switch to maybe an H2 buffer? Rifle locks back on empty mag now both suppressed and unsuppressed. Thoughts?
