Crosman Corporation introduced the M4-177 pneumatic air rifle that shoots both pellets and BBs. The M4-177 is a .177 caliber multi-pump air rifle, assembled in the USA.
The M4-177 comes equipped with a windage adjustable, dual aperture (2-position), flip rear sight, and an elevation adjustable front sight. The BB reservoir is located on the side of the receiver and holds up to 350 BBs. An 18-shot internal track feeds BBs into the action.
Using pellets, the precision, rifled steel barrel consistently delivers accurate groups. The M4-177 offers velocities of up to 660 feet per second (fps) with BBs and 625 fps with 7.9 grain, .177 caliber pellets.
