Faxon pencil barrels are the lightest in the industry. Don't take just their word for it, major companies like Robar, 2A Armament, and others choose Faxon pencils for their ideal balance of weight and performance.

Faxon has taken them a step further, adding in their patent-pending permanently attached SLIM muzzle devices. Shooters can choose from a three port muzzle device or three-prong flash hider, both allowing 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.
