Bronze armor, guest, from AZ, United States, asked on January 17, 2026

Are these barrels threaded for chokes? I'd like to screw and extension on the barrel to bring it up to 18 inches. Thanks

Okay, awesome! Going to thread on a muzzle brake over 4 inches and then (pin and weld) the muzzle brake on permanently to make the barrel over 18" (breech-face to muzzle end) before I get a Benelli. �

Cylinder is what you use for slugs. It’s like that for all shotguns.
