Faxon's Integral Rifle Barrels are 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 AR-15 build. With Faxon's Integral Muzzle Device Barrels 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, allowing the full assembly and disassembly of barrel and barrel nuts.
