http://www.winchesterguns.com/products/catalog/historic-detail.asp?family=009C&offset=%2D1&mid=511015


This nimble shotgun is built around a 2¾" action for unequaled speed and reliability. The Active Valve gas system cycles the lightest loads and reduces recoil for unbelievable follow-up shot accuracy. A removable LPA ghost-ring type rear sight mounts to the Weaver-style rail on the cantilever. TRUGLO® fiber-optic elements in the sights aid in target acquisition. Dura-Touch® Armor Coating improves grip on the composite stock and forearm. A compact 22" barrel and eight-round extended magazine make for fast handling. The Standard Invector™ choke system adds performance with slugs or shot. Two Active Valve pistons are included.
