Match Series Barreled Upper • Standard Configuration

12.5" Gunner Profile 6mm ARC Carbine-Length Gas Match Series Barrel MuzzLok® Flash Hider 10.75" M-LOK Handguard Made in Ohio

The Faxon Match Series 12.5" 6mm ARC Gunner Barreled Upper is the compact “do-it-all” option for shooters who want AR-15 handling with modern 6mm ARC performance. Whether you’re building a short hunting rig, a practical precision setup, or a lightweight field carbine, this upper keeps the package tight while maintaining the component quality and consistency you expect from a true manufacturer.

This is a standard barreled upper configuration (not the suppressor-ready variant) built around Faxon in-house parts and assembly practices. It ships ready to run with a fixed .750" low profile gas block and a carbine-length gas tube installed, plus a MuzzLok® ported 7.62 flash hider and a 10.75" Streamline M-LOK handguard for a clean, modern front end.

Want to run suppressed? You can absolutely add a suppressor to this upper, but most customers will get the best results by upgrading to an adjustable gas block and selecting one of our PLAN B compatible MuzzLok® muzzle devices to match their mount and tune for backpressure.

Best for: compact 6mm ARC builds, field carry, hunting-oriented AR-15 setups, practical precision.
Not for: buyers expecting a complete firearm (this is an upper assembly) or buyers who want factory adjustable-gas tuning out of the box.
