The Crosman M4-177 .177 caliber BB or pellet multi-pump air rifle (brand part no. M4-177) looks and handles like an M4 carbine but runs on air you pump yourself, with no CO2 or battery needed. It comes from Crosman and shoots steel BBs or pellets, so you can use whichever ammunition you have on hand. Pump it from 3 to 10 times, with more pumps giving higher velocity and fewer making for easy all-day plinking. The bolt-action rifle has a manual safety, an adjustable stock and Weaver/Picatinny rails for adding sights or accessories. It suits casual plinking and informal practice.
