Threaded Barrel
Many shooters enjoy the fitting silencers to their Ruger™ 10/22 Magnum rifles for quieter shooting. Our 10/22 Magnum threaded bull barrels use the popular thread pitch of ½-28 x .400 that is compatible with many favored silencers and other barrel-end accessories on the market. Each FJF threaded barrel comes with a rubber gasket and a matching thread protector. Additional thread protectors are available for purchase.

Williams Sights
The installed Williams Sights are available only through FJF and come pre-installed with screws and blue Locktite. Our custom 2-part sights will help improve your shooting experience with a single red fiber optic in front and dual green fiber optics in the back.

Matte Black Finish
Our 10/22 Magnum threaded bull barrels look as good as they shoot. Our matte finish for 4150V chrome moly vanadium steel is evenly applied with media blasting and blackening technologies that give our matte barrels a low reflectivity with diffused highlights. The coating will provide years of hard-wearing protection and corrosion resistance to your rifle.
