Full-auto .22s- anyone have one?

Hkmp5sd thanks. I had wondered about that, not that I'm ever going to throw away original parts. I fussed for days before I enlarged the hole in the rear site by 1/32 of an inch.

But the barrel length question is moot in an Uzi because the only other barrel length is a 16 inch barrel and it will absolutely not fit into an SMG. The conversion kit .22 barrels are 10 inch just like the original ones and cutting them off would mean not enough barrel sticking out the front for the classic Uzi look.

But Uzis have interchangable stocks. So you couldn't throw away the original folding stock if you put on a wooden stock with your .22 kit because it would change the overall length of the gun.

I don't have one, but I have shot one. A company by the name of Lakeside Machine makes full auto .22 replicas of the Browning 1917, 1919 and M2 machine guns. I shot one of the 1919 replicas. Man was that FUN!

This is not true.
1. As an individual you could not alter your machine gun post 1986 to change the parts used. The sear used in and of itself is a machine gun...so you can't just ditch the sear and build a new one to engage a different bolt...as you would then have multiple machine guns as you would have multiple sears.

Now if you FCG can interact with the various caliber conversions whereby the lower stays intact and you are not moving the trigger pack, all you are doing is switching a barrel...you are fine and good to go...but if you have an HK sear gun and the sear is registered for 9mm, you could NOT take that sear/trigger pack and move it to another host gun in say 5.56...without being in violation of Federal law. That's why you see so many HK sear guns listing registered in 9mm, 5.56, and 7.62....so you CAN swap calibers without being in violation of Federal law.

2. Using the AR15/M-16 as an example if you take your sear out of the registered host gun, you now have TWO machine guns...a no no. Mill and drill a new receiver to accept your sear, you now have 3 machine guns....ATF has ruled that drilling the hole in the instance of the AR family is making a post sample machine gun.

You have to be VERY careful when you tell people "ohh it's OK to have multiple calibers for the same FCG...it REALLY depends on the wepaon system in question.

ATF has the opinion that if you have all of the parts under your control to assemble a given firearm, you are in possession of that firearm. If you throw away the parts needed for your machinegun to match the caliber listed on the Form 4 and replace them with another caliber or alter the firearm so it can no longer use those parts, that would be a permanent change from their viewpoint and you would need to update the Form 4.
