Faxon 16″ Pencil Profile AR15 Barrel, 556 Nato w/ Integral Slim 3 Port Brake

16″ OAL with Integrated 3 Port Brake!

Faxon 16″ Pencil Profile AR15 Barrel, 556 NATO w/ Integral Slim 3 Port Brake is the perfect choice for any shooter who is looking for the maneuverability of a shorter overall length but wants the compatibility and versatility that comes with an AR15 build. This new offering from Faxon integrates a slim 3 port muzzle brake into the 16″ overall length of the barrel; customers will no longer be locked into a single configuration on their rifle build, or be dependent on finding a capable gunsmith to pin & weld their muzzle device to their barrel. Shooters can choose from a 3 port muzzle device or slotted flash hider.  This allows the full assembly and disassembly of gas blocks and barrel nuts. Shooters are forever free to change their weapon’s configuration.

Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave. Faxon’s 16″ 5.56 NATO AR15 Pencil Barrel with integrated 3 Port muzzle brake is fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.

Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

Do you need assistance in choosing the right barrel for the job?

This barrel is also offered in a Gunner Profile
