Folding stock adaptor ok with a pistol build?

[Tim K]

I guess the title says it all. Any legal issues with using a folder on a pistol build?

I hope not...for a friend...

But seriously there are many pistols you can buy with folding stocks from the factory and I am pretty sure there's no OAL to worry about with that kind of build.

My only comment is. IF one is running a "pistol" why add the extra 1.5-2" of length to something you wanted as short as possible. IF you're considering a law, or other folder like it.
I added the law side folder to one of my sbr's, stayed on about 30 minutes before it was removed. For side folders, i went with the foxtrot mike bufferless 12" uppers with a sig folder.

The issue I have previously seen with this is the folding assembly (for instance, the LAW folder) potentially made the brace length-of-pull too long and thus it "may" be considered a stock. Now, I don't know how any of that shakes out with the ATF now and what their rules are.

None of this is to say that's the rule, was the rule, or even makes any sense. That was simply the issue that I ran across when looking at this very question previously. Ultimately, the point is the folder concept wasn't an issue, but instead the mechanism of the folder made it an issue, especially with an SBA3 or SBA4
