Twice today, I chambered a round like usual, and the trigger would not budge. I ejected the round, reloaded it, and it fired.
I tried to make sure I was holding the loop in a tight enough grip so the little "interlock" stud that prevents firing with an open breech was pressed tightly.
The only other thing I can think of is the o-ring I have on my manual safety button on the left of the receiver. The idea is it keeps the safety button always in the "fire" position, removing a lawyered design feature.
Has this happened to you ? Any ideas ? Thanks, guys !
