Thread: AR-15 Bump firing

Does the Timney AR trigger have a couple of very small grub screws that tighten down on the trigger location pins that go through the lower? The one in my 10/22 does, and if the screws come loose, it will fire a round as you squeeze the trigger, and then another as you release the trigger. Tighten the grub screws and the problems goes away [on the 10/22]
