For a new generation of shooters who like the adaptability of the AR platform, the M4-177 is sure to impress. Looks and feels like an M4 firearm. Featuring a rifled steel barrel, the M4-177 shoots both pellets and BBs, so you can use whatever ammo you've got on hand. Since it's a multi-pump, you can pump it up to 10 times to get higher velocities or less if you'd like to do some easy all-day shooting. The rifle's variable pump action is easy to use for right or left-handed shooters, and velocities are exceptional at up to 625 fps with pellets and a swift 660 fps with BBs. The various picatinny rails allow you to mount your favorite accessories.
