Faxon Match Series 10/22 Heavy Rimfire Barrel 18.5″ 416R SS Nitride Threaded

The Faxon Match 10/22 Heavy rimfire barrel in 18.5 inches, 416R stainless with a nitride finish and a threaded muzzle, is built to bring precision, durability, and a sleek aesthetic to your Ruger 10/22 platform. Precision machined from 416R stainless steel and treated with a black nitride finish, it provides long-lasting corrosion resistance and an exceptional balance of weight, rigidity, and accuracy.

The 10/22 is the most modified rifle in America, and the barrel is the single component that changes accuracy the most. This is a no-frills, high-performance answer to that upgrade.

What the Faxon Match 10/22 Heavy Barrel Delivers

Whether you are building a dedicated target shooter or upgrading an existing rifle, this barrel offers impressive performance in a clean package. With a full 18.5 inch length, the heavy profile enhances velocity and sight radius while minimizing barrel whip and vibration. The result is consistent shot placement and improved downrange accuracy.

That makes it an ideal choice for rimfire competition, small game hunting, or long days at the range where a stock pencil barrel starts stringing shots as it heats. Precision rimfire shooters, benchrest competitors, and anyone chasing tighter groups from a favorite 10/22 are the people this barrel was designed for. It is also a natural centerpiece for a first serious build.

Specifications and Why They Matter

416R stainless is not the same as ordinary 416. The R designation indicates a modified alloy formulated specifically for rifle barrels, offering better toughness at low temperatures and superior machinability for the fine internal work that makes a bore consistent. Nearly every serious match barrel maker starts with it for exactly those reasons.

The 1:16 twist rate is optimized for .22 LR, ensuring reliable bullet stabilization across a wide range of standard and match ammunition. Heavy profile means more steel around the bore, which resists both the harmonic whip that opens groups and the heat buildup that shifts point of impact. The Faxon Match 10/22 Heavy barrel gives up a little carry weight and buys measurable consistency in return.

Installation, Care, and Compatibility

Barrel swaps on the 10/22 are among the easiest jobs in the firearms world. Clear the rifle, remove the barrel band and the action from the stock, back out the V-block screws, slide the old barrel out, and reverse the process with the new one. Torque the V-block screws evenly to specification so the barrel seats squarely in the receiver.

Confirm stock fit before you order, because a heavy profile barrel requires a stock with a barrel channel cut for it. Factory sporter stocks will not clear it without inletting. A threaded muzzle needs either a thread protector or a device installed at all times to protect the threads, since damaged muzzle threads are a genuine headache.

Ammunition testing is the last step and the one most owners skip. Rimfire barrels are famously particular, and the same Faxon Match 10/22 Heavy barrel that shoots one brand of match ammunition into a ragged hole may open up noticeably with another. Buy a box each of three or four different loads, shoot them over the same session from a rest, and let the target tell you what to stock up on for the season.

Clean the bore with a pull-through or a coated rod from the chamber end to protect the crown, and re-zero your optic after installation.
