Buy Refurbished & Save $$ The Refurbished M4-177 Tactical Air Rifle looks and feels like an M4 firearm. With the ability to shoot either BBs or pellets, you can use whatever ammo you've got on hand. Since this rifle is a multi-pump, you can pump it up to 10 times to get higher velocities or less if you'd like to do some easy all-day shooting. Get extra clips (same ones used by the Crosman 760 Pumpmaster) and load up so you don't have to interrupt your range time with a lot of reloading. A neat kit that gets you shooting the minute the box arrives! Includes everything for family shooting fun, indoors or out.
