All:
I put together an AR last spring with the following parts: LAR Grizzly lower DPMS LPK Bushmaster Patrolman Upper (M4A3) I have yet to fire any 5.56 out of the rifle. Have been using my CMMG .22lr conversion bolt kit. My problem is that my trigger pivot pin keeps backing out of the receiver. The pin usually back out and the end that protrudes through the left side of the receiver slips out of its hole inside of 100 rounds. I installed the LPK using a good video I found on YouTube (the guy has built tons of AR's). What could be causing my problem? If I'm having trouble firing .22lr, I assume the problem would be worse with the heavier recoil from a 5.56 round? Thanks, AV1611 out... |
