The 5.5-inch alloy-steel bull barrel is unfluted and crowned recessed, adding weight at the muzzle for steadier off-hand shots while protecting the rifling. Its matte blued finish matches the upper receiver for a clean, uniform look.
The polymer 22/45 frame keeps overall weight around 32 oz. while maintaining the 1911-style grip angle, checkered panels, and left-side magazine release many shooters prefer.
Sights consist of a ramped front blade and a fully adjustable square-notch rear, offering a precise sight picture for bullseye or small-game work. The included optics rail allows easy installation of red-dot or scope systems without gunsmithing.
Ruger’s stainless-steel bolt runs on the straight-blowback action that has made the Mark-Series a benchmark for rimfire reliability. Integrated safety features include a manual thumb safety, magazine disconnect, and loaded chamber indicator.
