Faxon Match Series 6mm ARC Complete Upper - 16" Gunner - Mid-Length

The Faxon Match Series 16-inch 6mm ARC Gunner Complete Upper is a fully assembled upper receiver group built around one of the most capable cartridges in the AR-15 platform — Faxon's Match Series Gunner profile barrel in 6mm ARC with mid-length gas, a superfinished 6.5 Grendel/ARC Type 2 BCG, Breek Sledgehammer gas-blocking charging handle, MuzzLok ported flash hider, and a 15-inch M-LOK handguard, ready to mount on a mil-spec lower.

The Faxon Match Series 16-inch 6mm ARC Gunner Complete Upper is a complete upper receiver group chambered in 6mm ARC, featuring a 16-inch Match Series Gunner profile barrel (4150 CMV, button-rifled, stress-relieved, MPI inspected, 1:7.5 twist, Nickel Teflon extension), mid-length gas system with fixed low-profile gas block and stainless gas tube, Faxon MuzzLok ported flash hider (7.62 steel, nitride), 15-inch Streamline M-LOK handguard, enhanced forged AR-15 upper receiver, superfinished 6.5 Grendel/ARC Type 2 BCG (.136-inch bolt face, nitride), and Breek Sledgehammer gas-blocking charging handle. Made in Greater Cincinnati, Ohio.

6mm ARC (Advanced Rifle Cartridge) was purpose-engineered by Hornady to deliver long-range ballistic performance from a standard AR-15 platform — it operates in the same bolt and magazine envelope as 6.5 Grendel but with a 6mm projectile that produces flatter trajectories, higher velocities, and excellent retained energy at distance. The 6mm ARC's ability to stabilize heavy, high-BC projectiles in the 80-108 grain range gives AR-15 shooters genuine 600-1000 yard capability from a platform that weighs and handles like a standard carbine. Faxon's Match Series barrel specification starts with 4150 CMV steel, button-rifled in-house for dimensional consistency, stress-relieved, and MPI inspected before shipping — each barrel verified for structural integrity before it leaves the factory. The 1:7.5 twist rate is optimized for the 6mm ARC's projectile weight range, stabilizing the heavier long-range bullets that define the cartridge's performance advantage. The Nickel Teflon barrel extension reduces friction between the bolt and the extension during cycling, contributing to reliable feeding across the cartridge's full performance range. The Gunner profile trims front-end weight while maintaining the rigidity needed for practical precision, keeping the upper balanced for extended field carry. The superfinished 6.5 Grendel/ARC Type 2 BCG provides the correct .136-inch bolt face for the 6mm ARC cartridge in nitride finish; the Breek Sledgehammer charging handle's gas-blocking design reduces gas blowback to the shooter's face during suppressed or high-volume firing. The MuzzLok ported flash hider reduces flash signature and muzzle rise. Made entirely in Ohio.
