Faxon Firearms Rimfire Pencil Barrel .22 LR 16" 10/22 - Salt Bath Nitride

The Faxon Firearms Rimfire Pencil Barrel is a drop-in replacement barrel for the Ruger 10/22 platform chambered in .22 LR. Built from 416-R stainless steel and finished with salt bath nitride, this 16-inch pencil-profile barrel is engineered for lightweight handling and long-term corrosion resistance in the field or at the range.

Faxon machines this rimfire barrel with 6-groove rifling at a 1:16 twist optimized for standard and high-velocity .22 LR ammunition. The muzzle is cut with a recessed target crown to protect the bore and support consistent accuracy. Every barrel is magnetic particle inspected before leaving the line to verify material integrity.

This barrel is threaded 1/2x28 for compatibility with standard rimfire muzzle accessories and is a direct-fit upgrade for the Ruger 10/22 action. The slim pencil profile keeps the rifle light and well-balanced, making it a smart choice for plinking, small-game hunting, and lightweight trainer builds.
