The Ruger™ 10/22 rifle has been popular for almost 50 years. Many gun enthusiasts begin with this model and often come back to it. There is always room for improvement concerning factory barrels, which is where FJF match-grade 10/22 Magnum rifle barrels come in. Our precision-manufactured 10/22 barrels are milled from 4150V chrome moly vanadium steel with the precision and quality expected from F.J. Feddersen. Adding one of our rifle barrels is like getting an instant upgrade that improves the accuracy of your shooting.

Threaded Barrel
Many shooters attach silencers to their 10/22 Magnum rifles for quieter shooting. Our threaded barrels use the thread pitch of ½-28 x .400 that is compatible with many standard silencers and other barrel-end accessories. Each FJF threaded barrel comes with a rubber gasket and a color-matched, knurled 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 that seem to glow using ambient light.

Fluted Bull Profile
Fluted 10/22 rifle barrels can weigh less than non-fluted barrels. Fluting adds surface area to a barrel for potentially more efficient cooling. Fluting also looks great adding interest to your 10/22 rifle.

Matte Black Finish
Our 10/22 rifle barrels look as good as they shoot. Our matte finish for 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.

Compatible with 10/22 Magnum rifles with .920 profiles. Our drop-in 10/22 barrels slip into your existing 22 Magnum receiver and interchange easily with the factory barrel.
