Faxon Firearms Match Series Gunner Complete AR-15 Upper Receiver - 6mm ARC - 12.5"

The Faxon Firearms Match Series Gunner Complete AR-15 Upper Receiver in 6mm ARC at 12.5" brings Hornady's long-range cartridge to a compact carbine-length platform, pairing a Match Series Gunner barrel with a Type 2 ARC BCG and gas-blocking charging handle.

Features:

• 12.5" 4150 CMV Gunner-profile barrel, button-rifled, 1:7.5 twist, Nickel Teflon extension
• Carbine-length gas system, fixed low-profile gas block
• Faxon MuzzLok ported flash hider, nitride
• 10.75" Streamline M-LOK handguard
• SuperFinished 6.5 Grendel/ARC Type 2 BCG, .136" bolt face, nitride (included)
• Breek Sledgehammer gas-blocking charging handle (included)

6mm ARC stabilizes heavy, high-BC 80-108 grain projectiles for genuine 600-1000 yard capability from a platform that still handles like a standard carbine, and the 1:7.5 twist is matched specifically to that weight range. The Breek Sledgehammer's gas-blocking design cuts gas blowback to the shooter's face during high-volume or suppressed firing, though this carbine-length gas system on a 12.5" barrel should have its tuning verified before suppressor use.

The Gunner profile trims front-end weight while keeping the rigidity needed for practical precision, and the barrel is stress-relieved and MPI-inspected before it ships to verify structural integrity.

Faxon Firearms manufactures and assembles every barrel in-house at its Cincinnati, Ohio facility, keeping quality control in-house from rifling through final inspection.
