10/22 Double Discharge?

Check your sear and disconnector -- those are the only 2 parts it could be.

Without having any parts in front of me, I couldn't tell you for sure what might be happening. I'll have to strip mine down and fool with it a bit.

Or maybe someone who's experienced this can tell you for sure.

I agree, COBrien. It just has to be in that part of the assembly. I'll tear into it tonight & see what the heck is going on in the assembly...

supposedly - you can MAKE a mini 14 do this intentionally with a staple stuck in a strategic location within the trigger pack. not sure how similar the trigger mechanism is with a 10/22

logic would dictate that a foreign object could do it too if it got lodged in just the right place...

if the rifle is newish... maybe a little bit of metal left from construction found its way in there?

It could be a bump fire. My 10-22 will double when I am going for group and the trigger finger stops and stays there after the first shot. The small rebound/recoil cause the gun to fire again.
I have a M100 Winchester 308 that I have to sight in with one round at a time. If I have two rounds, one in the chamber and one in the mag, it will double. In both cases it is follow through. I don't grab thee trigger. Squeeze, squeeze,.............bang! ..... surprise release and your finger is in the way when the gun returns to original place.

COBrien, that is correct...either the hammer/sear engagement is failing somehow, or the disconnector isn't resetting the sear. There aren't many other possibilities. This trigger assembly did have a trigger job performed on it by a very reputable gunsmith, so it has a lighter pull than a typical factory trigger. I'm hoping the problem was due to a small foreign object. I'll find out when I get back to AZ in a few days...

Didja ever get it figured out?
