The gas-operated Active Valve System cycles a wide variety of loads, and reduces felt recoil vastly better than inertia-operated systems. The entire shotgun is fully concealed in Mossy Oak® New Break-Up® camo with Dura-Touch® Armor Coating for superb grip, feel and protection. The bolt is plated with electroless nickel for reduced friction and added corrosion resistance, while the fast swinging barrel features the Invector-Plus™ choke tube system and .742″ Back-Bored Technology for optimal patterning. Three choke tubes (Full, Modified and Improved Cylinder), two length of pull stock spacers, drop and cast adjustment shims and sling swivel studs are included.
