The F12 is a semi-automatic gas operated shotgun with familiar AR/M4 ergonomics and controls. Built on a machined aluminum upper and lower receiver with built in attachment points for a host of accessories and optics. The chrome-lined barrel is chambered for up to 3" shells and features the Benelli/MobilA(R) choke tube system for added versatility. The F12 utilizes an AR-15/M4 style pistol grip and buttstock that can be changed with most aftermarket parts to further enhance the fitment of the shotgun to any shooter. Fed from the affordable and reliable T-1919 pattern shotgun magazine this offers the ability to carry the right amount of ammo for any situation from low-capacity mags for hunting or states with restrictions.
