Crosman M4-177 Multi-Pump Pneumatic Air Rifle – .177 Caliber Pellet/BB

The Crosman M4-177 is a multi-pump pneumatic air rifle that delivers variable power based on pump strokes, making it ideal for target shooting, plinking, and small pest control. Styled after modern sporting rifles, it uses no CO2 cartridges—just pump action for reliable, cost-effective shooting sessions.

Built with a synthetic stock and forearm, this rifle fires both .177 caliber pellets and steel BBs from a dual-ammo reservoir. Velocity reaches up to 660 fps with pellets (10 pumps), offering enough energy for backyard targets and pest birds at close range. The adjustable rear sight and fixed front post provide basic but functional open sights for learning marksmanship fundamentals. Lightweight and easy to pump, the M4-177 is a practical choice for younger shooters and adults looking for an affordable, no-fuss airgun.
