The Faxon Firearms 5.56 NATO 16" 1-8 twist pencil barrel with flash hider is built for shooters who refuse to compromise between handling and capability. A pencil profile barrel shaves weight without sacrificing the versatility that makes AR-15 platform rifles so practical—whether you're running drills at the range, hunting, or building a lightweight do-it-all rifle. The 1-8 twist rate handles everything from 55-grain varmint rounds to heavier service loads, making this a genuinely flexible choice for 5.56 shooters.
What sets this barrel apart is its integral flash hider, which means you keep full control of your setup. Unlike traditional barrels that force you into a single muzzle config or require a gunsmith to pin and weld, this design lets you swap components and reconfigure your rifle on your own. The gas block comes off, the barrel nut comes off—you build it your way, when you want. The mid-length gas system is forgiving and keeps the action smooth across various ammunition weights and conditions.
The narrow profile of the pencil design comes through both forward and aft of the gas block, cutting every ounce of unnecessary weight. Faxon magnetically particle inspected the barrel to catch internal defects before they matter, and the M4 extension ensures rock-solid compatibility with standard upper receivers. At 16" total length with the integral device installed, you get a barrel that's genuinely handy in tight quarters while staying on the right side of federal regulations.

Yes. The barrel features an M4 extension, which is the standard for AR-15 upper receivers, ensuring straightforward compatibility with most modern uppers.
