Faxon Firearms Match Series 6mm ARC Gunner Barreled Upper - 16"

True AR-15 compatibility with genuine long-range reach — the Faxon Match Series 6mm ARC Gunner Barreled Upper gives precision-focused builders the barrel, receiver, handguard, and gas system already assembled, while leaving BCG and charging handle selection to you.

The Faxon Match Series 16" 6mm ARC Gunner Barreled Upper is an AR-15 barreled upper assembly featuring a 416-R stainless Gunner-profile 6mm ARC barrel, mid-length gas system, 15" Streamline M-LOK handguard, and MuzzLok Ported 7.62 flash hider — without a BCG or charging handle included.

6mm ARC was purpose-built by Hornady to extract more precision from the AR-15 envelope, using modern high-BC 6mm projectiles to deliver genuine long-range capability in a lightweight AR-15-sized package. The 16" Gunner profile balances stiffness and handling for a rifle that splits time between the range and the field. Mid-length gas system keeps recoil consistent and manageable for a 16" general-purpose build.
