The 20 in steel barrel is a smoothbore with a true cylinder bore, paired with a single brass bead front sight and no rear sight for fast alignment. It is chambered for both 2 3/4 in and 3 in shells, offering flexibility across common 12 gauge loads.
The under-barrel tubular magazine holds 7 rounds for a 7+1 capacity. The magazine tube extends nearly to the muzzle and is finished with a knurled end cap. The barrel ring secures to the magazine tube for a solid, proven setup. There is no bayonet lug and no heat shield.
The aluminum-alloy receiver is finished in black and locks up steel-to-steel at the barrel extension. Controls include a tang-mounted sliding safety and an internal hammer. Ejection is to the right side.
Furniture consists of a black polymer pistol grip with finger grooves and a ribbed synthetic forend for a positive pump stroke. The metal wears a blued finish, and the shotgun is marked North Haven, Connecticut, USA, underscoring its U.S. manufacture.
