I was cleaning my gun tonight. Pressed down on the gas plug detent pin to screw in the Tac47 Autoplug and it's jammed in there. Any ideas on how to get it out? With it stuck in the depressed position, the Autoplug will spin til tight, but not be lined up properly, obviously. I tried tapping on the side of the block next to the detent pin to try and knock it free, but no luck.
