Faxon 300 Blackout GUNNER 10.5 Pistol Barrel

Manufactured by Faxon U.S.A

Faxon 300 Blackout Gunner 10.5 Pistol barrel is the pinnacle of performance, weight, balance, and value. It is designed by their competition shooting staff for those who value performance and versatility.  Therefore, the Gunner profile is a blend of two of the best performing profiles of all time, SOCOM and Pencil.

Proving that every once and awhile, the Government can do something right, the Gunner’s profile from the extension to the gas block mimics that delicious taper. From there, common sense takes over and the Gunner moves to a .750″ gas block journal and their famed pencil profile out front.  Also, removing the weight from the front of the barrel ensures maximum versatility.  As a result, it keeps material to the rear to maximize heat resistance and mitigate whip.

Monmouth Reloading is proud to team up with Faxon!  Since they make their products in house, they offer a great value without the extra costs.  So, be sure to check out our Bolt Carrier Groups, and upper receivers.  Furthermore, Monmouth offers a fine selection of handguards to compliment your Faxon barrel.  Another interesting offering are the handguard combos.
