AK 22 doubling

[crabo]

A friend of mine has an AK that shoots 22s. I am not sure of the model and specifics, but this is what he told me is happening.

Does anyone have any advice for him?

"Basically, it doubled a couple of times with the original fire control group, so I got a Tapco G2 single hook FCG, to see if that would help. NOT.

I have determined it's a problem with hammer follow, combined with an unsprung firing pin which is longer than the bolt, so when it follows, the hammer holds the FP out n front of the breechface so slam fires occur, this is more frequent with lighter ammo.

So, I'm fiddling with springs, trying to weaken the hammer spring. The factory part for this gun is a single wire one, the aftermarket one I got from Brownells ( I think it's Wolff) is made from 3 twisted wires, then wound to the shape of the original spring. I'm trying not to jack with the recoil spring yet, since the two I got from Brownell's are both a lot stronger than the original.

Basically, the hammer often fails to engage the disconnector. the slamfired cases have slightly bulged bases, so it's either not fully in battery or is bouncing out of battery as the round fires."

Thanks,

Interesting

I know some of the AK 's can double if you hold your finger just right and grip the rifle loosely
To allow the recoil to move the rifle back and forth agains your finger

As the gun bounces on your shoulder , the rebound off your shoulder will fire the rifle as the trigger hits your stationary finger
As the rifle moves forward

Might not be your problem

But just something to think about

I was under the impression that the .22 cal "AKs" were completely
different internally, just externally look like an AK.

ATF thinks you have a machine gun and need to go to jail. They have
actually done this to people, so fixing it is imperative.

Good luck !

I've got one of those Romanian .22 AKs. Never doubled, but it will actually trap empty brass in the receiver until it jams the bolt. The extra magazine that came with it won't go in the rifle, either. Poor design and QC.

Not trying to be a wise acre, but be very carefull here, a guy who had a rifle that had a malfunction and went auto due to a mechanical fault, is now serving time in prison thanks to ATF prosecution.

Have you replaced the disconnector spring? In a properly functioning AK, the disconnector should grab the hammer to prevent it from following. For a test:

Squeeze the trigger to Drop the hammer on an empty chamber, keep the trigger pulled rearward. Pull the bolt carrier all the way back with the charging handle, then let it back forward. The disconnector should grab the hammer and keep it down. When you release the trigger, you should feel a slight 'click' as the disconnector releases and the sear engages the hammer. The hammer should NOT fall.

You have a potentially unsafe firearm there, so if you can't fix it yourself, take it to an AK specialist who can help you out.

Go back and read more about the case. Go and read the ATF's analysis of the firearm. Guy had put selector, hammer, sear, etc. from an M16 in his lower. According to testimony, he told the kid he lent it to about the 3rd setting for the selector. Although the "burst" was not labeled on the lower, the switch was able to go into that spot. The kid, his friend, and others testified about being able to fire multiple shots per trigger pull in the 3rd selector setting.

Sounds like bubba wanted to make his rifle full auto without going through the hoops, and bragged about it to others. While I don't feel an automatic should be regulated any more than a standard single shot, we still have to play by the rules. I think bubba got caught in this case.

Seriously, the GOA and others make it sound like any of us could get in trouble for a malfunction. However, that was not the case. Bubba had made it malfunction intentionally so that it would be 'cool'. Want an M16? Go through the hoops and buy one. Don't go through your rifle, replacing parts here and there, trying to MAKE it play auto. You'll do the time, just like bubba here did.

I was pissed off until I actually went and read the documentation and testimony for myself.
