According to the Supreme court in Thompson Center vs ATF, common knowledge, and even ATF memo letters, it is legal to turn a handgun into a rifle.
Provided that a 16 inch (or greater) barrel is used, and the overall length is 26.0" or more.
OK, my question starts getting into the proper way to pin and weld a barrel to be in compliance with ATF reg's.
The barrel extension would be made of aluminum, but would be screwed onto the barrel, a hole drilled through the aluminum and down into the outer portion of the barrel and a steel locking pin inserted and then tig welded over top of the pin to prevent it from being removed without requiring tools to revert it back to a pistol.
OK, for a better explanation, I am thinking of pinning one of my silencers onto my scorpion permanently so I can add a stock without the need to double stamp the gun as an SBR. I could leave the front cap threaded so I can still clean the baffles every now and then as needed.
I stuck a rod down through the silencer and barrel until it bottomed out onto the closed bolt face. This is the method the ATF uses to measure barrel length.
If it were permanently attached, came out to a little more than 16 inches without the front cap.
I'm mainly just wanted to check with the welders here to make sure I can tig weld over steel inside of aluminum. I'm not trying to weld the steel to the aluminum. I already know that won't work. I am asking if I can weld over the steel to basically block it in there and keep it from falling out. Essentially blind pin it.
Now on to minimum overall length.
With an AR15 stock installed and extended would be about 36 inches, which is way more than the 26 inch minimum I would need it to be.
The factory carbine versions of the scorpion comes with a 16 inch barrel, and a folding stock from the factory, so ATF may not be measuring the overall length with the stock folded. I have asked on cz forum if someone could measure the OAL with the stock folded to give me a little better piece of mind because if atf is requiring 26 inches when it's folded (in its' shortest position), mine wouldn't be long enough and I would have to add a fixed stock instead of a folder.
But since a rifle, by both atf and legal definition is intended to be used as shoulder fired, I am inclined to believe they should measure to the end of the stock while it is extended. Which is part of the overall length in my humble opinion, but I would appreciate if anyone has a definitive answer of how to measure OAL with a folding stock if they would share it.
Oh, just for the record, here is a factory carbine. Mine wouldn't be identical, but it's worth noting that they are imported with folding stocks.
