Crosman M4-177 .177 Cal BB/Pellet Multi-Pump Air Rifle

The Crosman M4-177 is a tactical-style multi-pump air rifle chambered in .177 caliber that shoots both steel BBs and lead pellets from a single platform. A manual variable-pump pneumatic system powers the rifle, letting the shooter dial in velocity by stroking the bottom-mounted pump lever between 1 and 10 pumps for a power range of 350 fps up to 700 fps depending on pump count.

Built around a tactical AR-style layout with a black synthetic stock, the M4-177 pairs a bolt-action loading cycle with a pump lever for air compression, so no CO2 cartridges or batteries are required. The rifle carries a built-in 350-round BB reservoir in the magazine well and feeds pellets through a dual-ammunition rotary magazine, making it a flexible choice for casual plinking, backyard target practice, and introducing new shooters to airgun shooting.

Sighting is handled by an adjustable aperture rear sight with a matching blade front sight for zeroing in on the target. The rifle measures approximately 39.5 inches overall and weighs around 4.4 lbs, keeping it comfortable for extended range sessions. From Crosman, the M4-177 is a versatile, all-manual air rifle that adapts to the shooter's preferred power level and projectile on the fly.
