10/22 double-firing

[1377]

Sounds like its gummed up with residue in the bolt, break it down and clean the hell out of it.

+1 clean it

+1 on check with a couple different kinds of ammo.

Also, consider the user as part of the equation requiring analysis:
I didn't recall reading in the thread any discussion of your trigger work. Could you possibly have ridden the trigger so the disconnector does its thing but pressure was then re-exerted on the trigger thereby causing a second discharge from what you "intended" to be a single shot?
This would result in what seems to be a double but is actually 2 quick shots that only used enough trigger travel to engage the sear for shot 2.

It's quite easy to do and some handgun training exercises actually have perform that exact action (pull trigger, hold and release just until disconnector does it's thing, then re-exert pressure until second shot drops).

Just a thought...

I had it happen after I mounted a scope to the rifle. What happened was I applied thread lock and it dripped down right onto the firing pin and bolt which made it difficult to move freely. I would get lots of light strikes and mag dumps other times. Note to self, less thread lock.

Hopefully I'll be able to go test again soon, to see if a simple teardown/cleaining/inspection was all that was needed. However, another thought crossed my mind:

I usually store my rifles with the hammer/pin in the "down" or "fired" position. Is it possible that storing a 10/22 (with a heavy-hammer, VQ trigger group) like this could cause the constant compression and subsequent weakening of the firing pin spring? IF (and this is a big if) the firing pin spring were weakened, could this cause the pin to "bounce" and strike the primer when the bolt slams back into battery?

The ONLY other thing I can think of is that the overtravel adjustment in my VQ trigger group needs to be increased, but, as I said before, this is not a new rifle and I have never encountered this situation before.

Bingo, that is a likely culprit. If the Feds close in on you, perhaps you lost the gun in a hideous boating accident...........That seems to be pretty common lately.

Thanx, Russ

If it was the overtravel adjustment, (which it appears to have been and has since been adjusted), then there was nothing illegal about the weapon. The second shot was from the trigger being pulled a second time, due to a very shallow overtravel (and my poor trigger control). This also explains the inconsistency of the malfunction. Not to be calous, but I'm far more concerned about making sure my equipment functions correctly than I am about watching for black helicopters.
