The Faxon Match Series 16" 6.5 Grendel Gunner Complete Upper is built for shooters who want a true do-it-all AR-15 upper for hunting, practical precision, and distance work—without the weight and bulk of larger-frame platforms. 6.5 Grendel shines when you want better retained energy and improved wind performance versus 5.56, and this upper is configured to make the most of that advantage with proven Faxon components.

At the center is the Faxon Match Series Gunner Profile 16" Mid-Length 6.5 Grendel barrel, made from 416R stainless with 5R button rifling for consistent performance with quality projectiles. The Gunner contour keeps handling fast while maintaining practical rigidity where it matters. A mid-length gas system helps deliver a smoother impulse and reliable function—ideal for the shooter who wants accuracy without a harsh cycle.

This is a complete upper receiver group, assembled with the parts you actually want included: a Faxon Superfinished 6.5 Grendel/ARC Type 2 BCG (.136) – Nitride and a Faxon Edition Breek® Sledgehammer AR15 Gas Blocking Charging Handle. Up front, the system is finished with the Faxon MuzzLok® Ported 7.62 Steel Flash Hider – Nitride.

Best for: hunting rigs, DMR-style builds, practical precision, and shooters wanting a more capable intermediate cartridge in a standard AR-15 footprint.
Not for: buyers who want a bare upper only (this includes BCG + charging handle) or those expecting an AR-10 size platform.
