From the manufacturer

Faxon 14.5" Pencil 5.56 NATO Nitride Barrel with Slim 3 Port Muzzle Brake
Faxon pencil barrels are some of the lightest and high performing barrels in the industry. This unique 5.56 NATO chambered 14.5" barrel has a permanently attached Slim 3 port muzzle brake making the overall length of the barrel 16" and allowing the full assembly and disassembly of gas blocks and barrel nuts without ever having to go to a gunsmith. This barrel is manufactured 100% in-house from cradle-to-grave by Faxon Firearms. This barrel was fully stress relieved, air-gauge tested, and 11-degree target crowned to ensure superior accuracy. The barrel was made from certified 4150 Mil-Spec steel and finished in Nitride as well as checked for headspace by precision custom hardened gauges.
