Faxon Firearms .308 Win 16-inch Pencil Profile Barrel – AR-10

The Faxon Firearms Duty Series Barrel (brand part no. 10A810M16NPQ) is a 16-inch AR-10 pattern barrel chambered in .308 Winchester with a lightweight pencil profile. At just 1.78 pounds, it trims noticeable weight off the front of a .308 build compared to a heavier government profile barrel, while still delivering an 11-degree target crown for accuracy at the muzzle. Faxon finishes the barrel in nitride, cuts a mid-length gas port sized for a .750 gas block, and threads the muzzle for a compensator or flash hider. Built by FAXON FIREARMS, this barrel is a solid choice for a lighter-handling AR-10 build.
