The Umarex Ruger Mark IV .177 Pellet CO2 Air Pistol is a faithful, high-quality replica of the iconic Ruger Mark IV rimfire pistol — now in pellet form for superior accuracy and performance. This CO2-powered single-shot break-barrel pistol captures the original's striking design, original markings, and premium feel, complete with a high-gloss blued metal finish and textured polymer barrel sleeve for easy cocking.

The rifled steel barrel ensures excellent precision, while the height- and side-adjustable rear sight allows fine-tuning for consistent groups. The automatic safety locks the trigger when not in use, and the lightweight, balanced construction makes it comfortable for extended plinking, target practice, or training sessions.
