Rival Knockout Barrel/Muzzle
thingiverse
Manufactured for 8.5in 9/16 brass, this tool utilizes 2 4-40x 3/8in screws from a caliburn to securely attach the barrel and slide. First, reduce the stock slide/barrel spring to just loose (almost no preload) tension, then sand your brass as required. Step files are provided for convenience; feel free to design custom muzzles for attachment.
