Only way to eliminate the threaded muzzle is to pin and weld on a muzzle device.

The BATF accepted methods of attaching a threaded muzzle brake are to silver solder it on using high temperature silver solder, blind pin it in place with a hardened pin, welding or blind pinning and welding.
Did I get them all? |

So, just a 1/16" roll pin in the bottom of the brake going through the threads and into the barrel is sufficient? That would be great.

I've never heard of ATF accepting just a pin - the approved methods I've seen in writing are:
1) Silver solder with high temp (1100F) silver solder. 2) four or more equidistant spot welds 3) seam weld over 50% of the brake's circumference 4) blind pin and weld over the pin. Chemical adhesives and simple pinning (without welding over the pin) have never been approved to my knowledge. Dave_G: If you've got a reference to simple pinning being accepted, I'd appreciate a link. |

Quoted: 1) Silver solder with high temp (1100F) silver solder. 2) four or more equidistant spot welds 3) seam weld over 50% of the brake's circumference 4) blind pin and weld over the pin. Olympic does it differently. They use 4 set screws, that are Loktited in place, fitting into a groove that has been machined into the barrel. Mark |

budam is this on a threaded barrel. No, its not on a threaded barrel. Attached this way its actually removeable. You must permanently cover the threads and this way will not do. The barrel he speaks of is a postban. |

budam: As noted above, if there are no threads on the muzzle, the brake doesn't have to be permanently attached for post-ban legality.
The object of permanent attachment on a post-ban is to cover the otherwise forbidden 'threads for a flash suppressor' |
