Legal to thread a barrel?

[Ukraine Train]

I'm making a muzzle brake for my 91/30 Mosin Nagant. I can either thread my barrel or make the brake clamp on with set screws. I'd prefer the former but I'm not sure if it's legal.

Threaded barrels are an "evil feature" for semiautomatic rifles . . . at least until the AWB expires. No problem with a bolt action rifle. (Note that several manufacturers are making removable screw-on muzzle brakes.)

No problem with lever action rifles either.

Set screws are pretty pathetic, in my experience, expecially when they're subject to shock loading. They creep a little with each impact, and gouge whatever they're driven into.

Here's a suggestion: Make the part of the brake that slides over the barrel out of pipe, with a fairly close slip fit over the barrel. You can thread the pipe, and split it, and if you screw a pipe union onto it, it will clamp down amazingly.

Like others said, it's not a semi-automatic. You can thread the barrel, put a flash supressor (or muzzle break) on it, pistol grip, detachable magazine (just can't make a magazine that holds over 10 rounds I guess), grenade launcher, collapsable stock and bayonet.

The bayonet isnt the evil feature, the mount is...

So, in theory, if you duct-taped one to a post-ban AR, your still good, unless they count the duct tape as the mount...

Actully You an have threaded barrel on a semi-auto w/ detachable mag as long as it doesn't other "evil" features such as pistol gip or bayonet lug. Come to think of it(may be wrong) a semi-auto rifle can have every "evil" feature if the mag is permanetly attached.
