Crosman MK45 CO2 BB 20-Rd Semi-Auto Air Pistol

The Crosman MK45 is a CO2-powered BB air pistol built for casual plinking and backyard target shooting. This semi-automatic repeater chambers standard 4.5mm (.177) steel BBs from a quick-release 20-round drop-out magazine, driving them down a steel smoothbore barrel at velocities up to 480 fps.

The MK45 wears a dual-tone finish with a removable grip panel that pops off in seconds to give you quick access to the CO2 powerlet compartment underneath, no tools required. A simple fixed blade front sight and fixed notch rear sight keep aiming intuitive right out of the box, while the lightweight polymer construction keeps the whole pistol at about .63 lbs for comfortable handling.

At just 7.25" overall with a 4.5" barrel, the MK45 is a compact, easy-to-shoot air pistol that makes a great entry-level option for new shooters and a fun low-cost plinker for experienced airgunners.
