The M4-177 is Crosman's air rifle replica of the M4 firearm. This multi-pump gun has a lightweight ABS plastic frame with a plenty of Picatinny railspace and an adjustable crane stock. It shoots either steel BBs or .177 caliber pellets, with a 350 round BB reservoir so you'll never worry about running out of ammo again.

Why choose this gun?

• Variable pump action usable by both right and left-handed shooters

Pro Tip:
On a bolt action rifle, the bolt is manually operated by the opening and closing of the barrel with a handle. This type of firearm has an excellent balance of strength and tends to be more reliable and accurate, yet has a lower rate of fire than semi-automatic weapons.
