The Faxon Firearms Pro 6mm ARC AR-15 Rifle with a 16-inch barrel (Faxon Firearms part no. FXPRO6A16GA15) is a complete semi-automatic rifle built around the 6mm Advanced Rifle Cartridge. Faxon ships it fully assembled with a Match Series Gunner-profile barrel, a patented adjustable .750-inch gas block and a Type 2 ARC nitride bolt carrier group. A Schmid-made Enhanced Match Trigger and a Breek Sledgehammer charging handle come installed, along with a 15-inch Streamline M-LOK handguard. It suits precision shooters, hunters and suppressed builds that want a flat-shooting AR without assembling the parts themselves.

Key Specifications

• Chambering is 6mm ARC, a cartridge known for flat trajectories and strong wind resistance from an AR-15 platform.
• The barrel is a 16-inch Match Series Gunner profile, balanced for hunting and precision work.
• The gas system is mid-length, which gives a softer impulse than a carbine-length system.
• The gas block is Faxon’s patented adjustable .750-inch low-profile design, so the system can be tuned for suppressed or unsuppressed use.
• The bolt carrier group is a Type 2 ARC SuperFinished nitride unit with the correct bolt face for 6mm ARC.
• The trigger is the Faxon Enhanced Match Trigger by Schmid, a drop-in unit with a crisp, consistent pull.
• The handguard is a 15-inch Streamline aluminum M-LOK free-float design.
• The muzzle device is a MuzzLok Plan B compatible flash hider with 5/8×24 threads.
• The stock is a B5 Systems Bravo, paired with a B5 Systems pistol grip and an ambidextrous safety.
• The rifle includes one 10-round DURAMAG magazine and a Savior Specialist soft case.
