FAXON PRO 16" 6MM ARC AR15 RIFLE
PRO Line Complete Rifle • 6mm ARC • Made in Ohio
FAXON PRO 16" 6MM ARC AR15 RIFLE — FXPRO6A16GA15
6mm ARC 16" Gunner Profile Mid-Length Gas Adj. Gas Block Plan B Compatible Match Trigger by Schmid Type 2 ARC BCG B5 Bravo Stock Complete Firearm Made in Ohio
The Faxon PRO 16" 6mm ARC AR15 Rifle is a complete, ready-to-shoot semi-automatic rifle purpose-built around the 6mm Advanced Rifle Cartridge — a round developed with special operations input to deliver long-range precision performance from a standard AR-15 platform. Unlike a barreled upper or a parts kit, this is a fully assembled firearm that ships with magazine, case, and everything needed to head to the range.
6mm ARC demands a correctly spec'd platform. This rifle is built around a matched pair of Faxon Enhanced Forged AR15 Upper and Faxon Forged AR15 Lower Receiver, fed by a Faxon SuperFinished Type 2 ARC Bolt Carrier Group in Nitride — the correct bolt face and head spacing for 6mm ARC. Using a standard 5.56 BCG with this rifle is not supported.
The heart of the build is the Faxon Match Series Gunner-Profile 16" Mid-Length 6mm ARC Barrel. Mid-length gas gives the 16" tube a softer impulse curve than carbine-length setups, and Faxon's patented adjustable .750" gas block lets you tune the system precisely — especially important when running suppressed or switching between subsonic and supersonic loads.
The trigger is a Faxon Enhanced Match Trigger by Schmid® — a premium drop-in unit that raises the bar for factory-included triggers on a production rifle. The charging handle is the Faxon Edition Breek® Sledgehammer, a gas-blocking design that matters when shooting suppressed or in adverse conditions. The front end is finished with a MuzzLok® Plan B compatible flash hider (5/8×24, .375" bore) — a direct mount path for Plan B compatible suppressors without an adapter.
✔ Best for: precision rifle shooters stepping up from 5.56, hunters wanting a flat-shooting AR-15, suppressed builds on the 6mm ARC platform, competitive shooters who want a factory rifle with match-grade components.
✘ Not for: buyers who need a pistol-configuration (this is a rifle-length build with a 16" barrel and Bravo stock), those who already own a barreled upper and only need a lower, or buyers in states with magazine restrictions beyond 10 rounds (ships with 10-rd DURAMAG).
? Legal note: This is a complete firearm. Transfer must be completed through a licensed FFL dealer. Not available for direct shipment to consumers. Verify local regulations regarding rifle purchases before ordering.
Key Features
- Matched Faxon Forged Upper & Lower Receivers — Both receivers machined and matched by Faxon for consistent fit and finish. Enhanced forged upper features M4 feed ramp geometry; lower includes mil-spec tensioning screw for zero play.
- 6mm ARC Match Series Gunner Barrel — 16" mid-length Gunner profile provides the balance point and heat management of a slimmed-down contour with the gas dwell time of a mid-length system — the right combination for a rifle-length 6mm ARC build.
- Patented Adjustable Gas Block — Faxon's 3-screw .750" adjustable low-profile gas block lets you tune for suppressed vs. unsuppressed, and for different ammunition weights — a feature most production rifles omit.
- Type 2 ARC SuperFinished BCG — The Faxon SuperFinished Nitride BCG uses the correct Grendel/ARC Type 2 bolt face. The SuperFinished surface treatment reduces friction and improves cleanability.
- Enhanced Match Trigger by Schmid® — A factory-included match-grade trigger is rare on a production rifle at this price. The Faxon Enhanced Match Trigger by Schmid delivers a clean, crisp break that most shooters would upgrade to on an aftermarket basis.
- Breek® Sledgehammer Gas-Blocking Charging Handle — The Faxon Edition Sledgehammer blocks gas from reaching the shooter's face when running suppressed — a meaningful upgrade over a standard mil-spec charging handle.
- Plan B Compatible Muzzle Mount — The MuzzLok Plan B flash hider (5/8×24, .375" bore) provides a suppressor-forward mount path without the expense of an additional adapter.
- 15" Streamline M-LOK Handguard — The Faxon 15" Streamline runs nearly to the muzzle device on a 16" barrel, maximizing rail estate and providing the hand position most shooters prefer for precision or supported shooting.
- Ships Complete — Range-Ready — Includes DURAMAG 10-round 6mm ARC magazine, Faxon magazine marker bands, and Savior Specialist soft case. Add ammunition and complete your FFL transfer.

Frequently Asked Questions
Is the Faxon PRO 16" 6mm ARC a complete, ready-to-shoot rifle?
Yes. The FXPRO6A16GA15 is a complete semi-automatic rifle. It ships with every component needed to fire, including a 10-round DURAMAG magazine, Savior Specialist soft case, and Faxon magazine marker bands. You will need to purchase 6mm ARC ammunition separately. All firearm purchases require transfer through a licensed FFL dealer.
What makes 6mm ARC a good cartridge choice for an AR-15 rifle?
6mm ARC (Advanced Rifle Cartridge) was developed by Hornady in collaboration with special operations units. It delivers long-range ballistic performance — flatter trajectory and better wind resistance than 5.56 NATO — from a standard AR-15 platform using a modified bolt and barrel. The 6mm ARC operates from standard AR-15 magazine bodies with a dedicated follower and is well-suited for precision shooting, hunting, and suppressed applications. The Faxon PRO uses a Type 2 ARC bolt carrier group specifically matched to this cartridge.
Does the Faxon PRO 6mm ARC rifle come suppressor-ready?
Yes. The rifle is equipped with Faxon's MuzzLok Plan B compatible flash hider (5/8×24 thread, .375" bore), which accepts Plan B compatible suppressors directly. The Faxon patented adjustable gas block allows you to tune dwell time and backpressure for suppressed use with your specific suppressor and ammunition combination. The Breek Sledgehammer charging handle also helps manage gas when running suppressed.
What magazines does the Faxon PRO 6mm ARC rifle use?
The Faxon PRO 6mm ARC ships with a DURAMAG 10-round 6mm ARC magazine. The 6mm ARC cartridge uses a standard AR-15 magazine body with a modified follower designed for the .243-diameter projectile and its specific case head geometry. Standard AR-15 magazines with a 6mm ARC-compatible follower will function; using 5.56 or standard .223 followers is not recommended and may cause feeding issues.
What bolt carrier group does the Faxon PRO 6mm ARC use, and why does it matter?
The rifle uses a Faxon SuperFinished 6.5 Grendel/ARC Type 2 Bolt Carrier Group in Nitride finish. The Type 2 bolt is the correct specification for 6mm ARC — it shares the same bolt face and head spacing as 6.5 Grendel. The SuperFinished surface treatment reduces friction and wear while improving corrosion resistance. Do not use a standard 5.56/.223 bolt carrier group with this rifle — the bolt face diameter is different and will not properly support 6mm ARC case heads.
Where is the Faxon PRO AR15 rifle made?
The Faxon PRO is designed, manufactured, and assembled by Faxon Firearms in Greater Cincinnati, Ohio. Faxon has operated as a precision machining company since 1978. The barrel, upper receiver, lower receiver, gas block, gas tube, handguard, and charging handle are all Faxon-made or Faxon-branded components. Partner components — trigger (Schmid), stock and grip (B5 Systems), magazine (DURAMAG), and case (Savior Equipment) — are sourced from their respective original manufacturers.
