Thread: AR-15 Bump firing

It's a malfunction not some silly attempt to go full auto.

Cant hurt to take the bolt group apart and make sure the firing pin is sliding smoothly. I cant say I thought that much of the Timney AR15 trigger myself. While the small light hammer reduces your trigger pull they don't seem super robust.

Thanks for the replies even the mystifying ones. I have checked everything suggested and all seems ok I don't have the original trigger so I can't try that. To answer the last question I fired about 10 shots and it fired two shost twice both when the trigger was pulled not released.
