The gas-operated Active Valve System cycles a wide variety of loads, and reduces felt recoil vastly better than inertia-operated systems. Of course the big difference is that the entire shotgun is fully concealed in new Mossy Oak® Break-Up® Infinity camo — and then given a Dura-Touch® Armor Coating for superb grip, feel and protection. Take a look inside: the locking 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.
