The Faxon Ar15 Barrel 350 Legend in 16" with Gunner Profile is a versatile, mid-weight barrel built for AR builders who want a balanced platform for the increasingly popular 350 Legend cartridge. Faxon's Gunner Profile splits the difference between traditional Government-profile durability and Pencil-profile speed and handling—giving you a general-purpose rifle that doesn't sacrifice either trait. Machined from 4150 steel and button-rifled with a 1:16 twist, this barrel handles the subsonic and supers-sonic loads that make 350 Legend effective for hunting medium game and running drills on the range.
The 16" length pairs naturally with carbine-gas systems, making it a natural fit for compact, maneuverable builds without the bulk of a mid-length or rifle-length gas tube. The nitride finish inside and out provides corrosion resistance and durability typical of Faxon's no-frills, working-gun approach. At .750" across the gas-block journal, the barrel mates with standard gas blocks—no special adapters required. All Faxon barrels are MPI-tested to catch hidden flaws before they reach you.
The 1/2-28 TPI threaded muzzle accepts common AR suppressors, brakes, or flash hiders, so you can tailor the rifle to your mission. Whether you're building a hunting rifle, a short-range truck gun, or experimenting with 350 Legend's unique ballistics, this barrel delivers the balance of weight, handling, and strength that makes the Gunner Profile a favorite among serious AR builders.

Yes. The .750" gas-block journal is the standard size, so it's compatible with most common AR gas blocks without special adapters.
The barrel has a 1/2-28 TPI threaded muzzle, which accepts most standard AR suppressors, flash hiders, and muzzle brakes in that thread pattern.
The Gunner Profile is Faxon's hybrid design that combines the durability and reliability of Government-profile barrels with the lighter weight and improved handling of Pencil-profile barrels. It's ideal for builders who want a versatile, general-purpose rifle without sacrificing either toughness or maneuverability.
