Pick up the Winchester Super X Pump (SXP) shotgun offers the feeling of an inertia-assisted slide-action that can deliver three shots in a half second. Features a non-glare matte finish on the barrel and receiver; composite stock and forearm are up to tough conditions; the SXP action fires all factory 2 3/4" and 3" steel, tungsten, bismuth and lead loads through a chrome plated .742" Back-Bored barrel with Invector-Plus chokes.
