Umarex Ruger Mark IV CO2 Pistol – .177 Caliber Pellet, Black

The Umarex Ruger Mark IV is a CO2-powered .177 caliber air pistol built for target practice and recreational plinking. Officially licensed from Ruger, this replica faithfully mirrors the iconic Mark IV rimfire pistol in function and feel, giving shooters a cost-effective training platform or backyard plinker with authentic ergonomics and controls.

Constructed with a polymer frame and metal components where it counts, the Mark IV uses a single 12-gram CO2 cartridge housed in the grip and feeds from a removable 10-round pellet magazine. The single-action trigger breaks cleanly, and the adjustable rear sight pairs with a fixed front blade for sight picture refinement. Velocity reaches approximately 410 fps with standard .177 lead pellets, providing adequate energy for paper targets and cans at close range. The replica magazine release, ambidextrous safety, and textured grip panels replicate the handling characteristics of the firearm counterpart.
