The Faxon Firearms Big Gunner Barrel (brand part no. 10B863C16NGMHL5RNP3) is a 16-inch AR-10 pattern barrel chambered in 8.6 Blackout, machined from 416-R stainless steel and finished with a bead blasted surface. Faxon developed its 8.6 Blackout barrels in partnership with Q, the round’s originator, and cuts every one with a fast 1 in 3 inch twist that channels the bullet’s rotational energy into more retained energy on target. Every barrel is fully stress relieved, air-gauge tested, and magnetic particle inspected before an 11-degree target crown is cut at the muzzle for accuracy. Built by FAXON FIREARMS, this Big Gunner profile barrel is tuned for the heavy-bullet, subsonic-friendly performance that makes 8.6 Blackout stand out.
