Faxon 10.5″ Straight Fluted 416R SS Black Nitride Threaded 10/22 Barrel

The Faxon Straight Fluted 416R stainless 10/22 barrel in 10.5 inches with a black nitride finish is purpose built for rimfire enthusiasts who want serious performance in a compact, lightweight package. Designed and manufactured in house by Faxon, it brings match grade construction and precision engineering to one of the most modified rifles in America.

The 10/22 platform is endlessly customizable, and the barrel is where the accuracy actually lives.

What the Faxon Straight Fluted 416R Barrel Is For

At 10.5 inches this barrel is ideal for compact rimfire builds. That means suppressed plinking setups, short hunting carbines and lightweight range guns where handling matters as much as raw velocity. Rimfire cartridges reach most of their velocity in a short barrel anyway, which is why a build like this gives up far less than people assume.

The muzzle is threaded, so a suppressor or muzzle device installs without additional gunsmithing. Combined with subsonic ammunition, a short suppressed 10/22 is about the most enjoyable rifle you can own, and this barrel is built specifically for that role. From Faxon Firearms, the machining standard is the same one applied to their centerfire line.

Features That Set It Apart

This is a barrel with a clear design brief and no wasted material.

• Machined from 416R stainless steel, the standard material for match grade barrels.
• Salt bath nitride finish for corrosion resistance, extended barrel life and a non reflective surface.
• Straight fluted profile that reduces weight while adding rigidity.
• Increased surface area from the flutes for improved heat dissipation.
• Threaded muzzle ready for a suppressor or muzzle device.
• Compact 10.5 inch length designed and manufactured in house by Faxon.

Materials and Profile Explained

416R is a stainless alloy developed specifically for rifle barrels. It machines cleanly enough to hold match tolerances and it holds a consistent bore dimension, which is the foundation of accuracy. The salt bath nitride process then hardens the surface without adding a coating that can chip, which is why the finish resists both wear and weather.

Straight fluting is not decoration. Removing material in straight channels along the barrel drops weight while keeping the barrel stiffer than a slim profile of the same mass would be, and the extra exposed surface helps the barrel shed heat during long strings. On a light rifle that combination of stiffness, low weight and cooling is exactly what you want.

Installation, Suppressor Use and Care

Installing a 10/22 barrel is one of the easiest upgrades in the hobby. Remove the action from the stock, loosen the V-block screws, swap the barrel and torque the block evenly. Check headspace by confirming smooth bolt closure on a snap cap, and always confirm the rifle is unloaded before starting.

If you are running a suppressor, expect rimfire fouling to build faster than you are used to. Rimfire ammunition is dirty by nature, so plan on cleaning the chamber and the threads more often, and keep the thread protector on whenever the can is off.

Accuracy expectations are worth setting honestly. A Faxon Straight Fluted 416R barrel gives your rifle the potential to shoot well, but rimfire accuracy is enormously ammunition dependent. Buy several brands, shoot them from a rest at the same distance on the same day, and let the rifle tell you what it likes. Once you know, buy that lot in quantity.

Clean from the chamber with a coated rod and a bore guide, since the crown on a short barrel is doing a lot of work for your accuracy. Browse our parts and upgrades collection for the stocks, triggers and bolt components that turn this barrel into a complete build.

Light, stiff and threaded, the Faxon Straight Fluted 416R is the barrel a compact 10/22 project should start with. Ships direct to your door, no FFL required.
