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.
