Is a 16" 10/22 barrel. Legal

[kell]

I feel like a teenager all over again; Gas is cheap and I'm grounded..

Anyway, have taken this opportunity to clean up some old gun-stuff. Ran across a 16" threaded barrel, for a 10/22. My question/concerns is if it's legal to mount it on a standard carbine stock or even a collapsible/folding stock? I'm sure there are a number or If's and Buts, so what say you ??

Thanks and;

I used to check the paper every day and if anything interesting came up, I'd try to get it. I got a lot of really good pieces that way. Anyway this .22Mag Mare's Leg (that short rifle Steve McQueen carried) came up and I bought it. It's a pretty dumb little lever action sort of pistol. It's a Henry, and they'll sell you a butt stock to make a rifle. Now it's workable, but the barrel's too short. Prohibited just because I changed the stock. Makes me so mad I could spit. I have other words I'll keep to myself.
