Faxon 16 Legal SLIM Perm 3 Port Brake 14.5 GUNNER 5.56 NATO

Manufactured by Faxon U.S.A

Faxon 16 Legal SLIM Perm 3 Port Brake 14.5 GUNNER 5.56 NATO 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 .625″ 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.

Most importantly, this Faxon barrel has their patent-pending permanently attached SLIM muzzle device. Shooters can choose from a 3 port muzzle device or three-prong flash hider.  Because of this, it allows the full assembly and disassembly of gas blocks and barrel nuts.  Shooters are forever free to change their weapon’s configuration without having to go to a gunsmith. 

*Please note muzzle devices are attached permanently. Any attempt to remove the device will result in the destruction of the barrel and void all warranties.
