A neat kit that gets you shooting the minute the box arrives! Includes everything for family shooting fun, indoors or out.

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.

When you shoot steel BBs, do not shoot at hard objects or water. The BBs will ricochet! No matter what ammo you’re using, remember to wear safety glasses. Everyone in the vicinity of the range should wear safety glasses, even if they’re not shooting. Remember to remove all pets from the range before you start shooting.
