Montana,
The rifle would stove pipe, the shell would partially extract and the bolt would start to feed the next round. When I took the upper off and played with the gas system at the range I could get it to fire 3-4 rounds but the last shell would stay in the rifle and the bolt would be held back by the latch. I looked at some of the brass and the primers are showing pressure sign. 29.5gr of CFE223. A2
