View Full Version : Cutting a barrel

I just found a really good deal on a 16" barrel. Is it possible to cut down a 16" barrel to 14,5" and permanently weld a longer flash hider on it to make it legal? Is this something that can be done, or am I only asking for trouble?

If it can be done, does anyone know who does this?

Thanks

Yes it can be done and shouldn't be trouble. I don't know who to refer you to though.

Yes it can be done. Don't know anyone specific in Denver, but down here in the springs, either Earl Hickman or I could do it.

I was thinking of doing this same thing. But would it be possible to go one step further, have the short barrel threaded and the brake just spot welded into place? Kind of like they do on the AMD AK's. That way later if you decide to get a SBR stamp all that needs to be done is spot weld removed?

Sorry to the OP for whoring your thread but I thought I would just ask in here in lieu of making a whole new thread.

Thanks.

No problem su405, I was kinda thinking of the same thing anyway. I would rather have it threaded too, so good question. Anyone have an answer for this?

Thanks

As long as it is welded and not easily removable is the key.

a "blind pin" an option- welding is not required.. it has to be ground flat, and it doesn't go out the other side, so it's not removable without more drilling or grinding.

Sliver solder/brazing is also an option..

Sweet! This is what I was thinking but thought I'd ask to make sure.

Now to find a PRO for a decent price.

From ATF P 5320.8 ATF National Firearms Act Handbook page 17-

The ATF procedure for measuring barrel length is to measure from the closed bolt (or breech-face) to
the furthermost end of the barrel or permanently attached muzzle device. Permanent methods of
attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver soldering, or blind pinning with the pin head welded over. Barrels are measured by inserting a dowel rod into the barrel until the rod stops against the bolt or breech-face. The rod is then marked at the furthermost end of the barrel or permanently attached muzzle device, withdrawn from the barrel, and
measured.

It is available at

learned something new, have gotten bad info before that it could be press fit tight and ground flush... good thing I've never used that method..
