Faxon Rimfire 16″ Flame Fluted Bull Threaded 416R SS Nitride 10/22 Barrel

The Faxon Rimfire Flame Fluted 16 inch bull barrel in threaded 416R stainless with a nitride finish is designed to elevate both the performance and the appearance of your Ruger 10/22 build. It combines the strength of 416R stainless steel with Faxon precision machining to deliver accuracy and durability in a visually striking package. The bold flame fluting and black nitride finish give any rimfire rifle a custom look.

Plenty of barrels shoot well. Very few also make people at the range walk over to ask about them.

What the Faxon Rimfire Flame Fluted Barrel Brings

Start with the twist rate. Engineered with a 1:16 twist, the Faxon Rimfire Flame Fluted barrel is optimized for .22 LR performance and ensures consistent bullet stabilization whether you are shooting paper at 50 yards or plinking steel all afternoon. That is the correct rate for the bullet weights that make up nearly all rimfire ammunition.

The bull profile is the other half of the equation. A heavy contour resists the harmonic vibration that opens groups and it soaks up heat during high volume sessions, which is exactly the load a rimfire rifle sees. This barrel suits precision rimfire competitors, squirrel hunters who want a repeatable point of impact, and builders assembling a 10/22 that looks as good as it shoots.

Key Features

• 416R stainless steel construction with a black nitride finish for corrosion resistance
• 1:16 twist rate optimized for .22 LR bullet stabilization
• Bull barrel profile for rigidity and heat capacity during long sessions
• Flame fluting that reduces weight and increases cooling surface area
• Threaded muzzle for suppressors and rimfire muzzle devices
• 16 inch length that balances velocity, handling, and suppressor compatibility

Fluting, Finish, and Balance

Flame fluting is not just decoration on the Faxon Rimfire Flame Fluted barrel. The cuts remove material from a heavy profile without meaningfully reducing stiffness, and they increase surface area for better heat dissipation during extended shooting. The distinctive pattern also contributes to improved balance while maintaining the rigidity that makes a bull barrel worth having.

Black nitride is a surface conversion treatment rather than a coating, which means it cannot chip or flake off the way paint or a sprayed finish can. It adds hardness and corrosion resistance to the stainless underneath, and it produces a deep uniform black that contrasts sharply with the machined flutes.

At 16 inches, the barrel keeps a rifle handy while leaving room for a suppressor without creating an unwieldy package. Shorter rimfire barrels lose very little velocity, so this length is about handling and balance more than ballistics.

Installation, Care, and Compatibility

Fitting the Faxon Rimfire Flame Fluted barrel to a 10/22 receiver is a straightforward job. Back out the V block screws, lift the factory barrel free, seat the new barrel fully into the receiver, and torque the V block evenly so the barrel is held squarely. Confirm the barrel clears your stock channel, since a bull profile will not fit a factory sporter stock without relieving it.

Maintenance for a rimfire barrel is mostly about restraint. Clean from the chamber with a coated rod and a bore guide, use nylon brushes rather than steel, and expect to re zero after a thorough cleaning because many rimfire barrels settle in slightly fouled. Wipe the exterior down after handling to keep skin oils off the finish.

The threaded muzzle accepts common rimfire suppressors and devices, and a thread protector should be installed whenever nothing else is. Find stocks, triggers, and chassis parts to finish the build in the parts and upgrades collection. Faxon Firearms machines this barrel to the same standards as its centerfire line.

Accuracy, durability, and a genuinely custom appearance in one drop in part make this an easy recommendation. Ships direct to your door, no FFL required.
