Hello All,
Anyone know how the old Weaver muzzle break/compensator is attached to the barrel? The literature states it can be installed at the factory or by any competent gunsmith but doesn't state the method of attachment. Were they sweated on or was the outside of the barrel threaded?
I would ask over on "shotgun world" forum but cant login at the moment. Thanks

The Weaver choke 'body' is threaded onto the orig shotgun bbl.
(Gunsmith job to cut then turn to the correct dia and thread)

Both the 'body' and the interchangable choke tubes are aluminum.,,
at least they were on the ones I remember.

Weaver also made an adj choke that was more like the PolyChoke.
Once piece ( no separate tubes) and you simply twisted the barrel of the choke to adjust to the different choke settings. Those were steel IIRC.

Thanks for the reply. I briefly tried unscrewing the body (with no success) before I posted my question. I will soak it with some CLP or Liquid wrench and try again. Right hand thread I assume. Thanks again for the information.

Yes RH thread.
They were installed extremely tight to avoid any chance of the body coming unscrewed with the constant install/removal of the choke tubes.
I'd bet that some had thread lock'r on the threads when they were screwed into place just to 'make sure'.

If you do remove the body, the last inch or a bit less of the bbl will be threaded.
So if your intension is to leave the Weaver choke off entirely and make a plain bbl gun with a cyl choke, most are just cut off right behind the choke body.
Then crown the bbl.

That leaves you with the choke body with a piece of the bbl still stuck inside it and really hard to remove if you have intentions of reusing it or reselling for reuse.
