Ruger Mark IV 22/45 .22 LR 5.5" Bull-Barrel Pistol with ADE Picatinny Rail | Two 10-Rd Mags
The Ruger Mark IV 22/45 pairs the classic Mark-series bull-barrel accuracy with a lightweight polymer grip frame that mimics the angle of a 1911. This 2022-manufactured example adds an aftermarket ADE Picatinny mini-rail already installed on the receiver, giving you a ready platform for reflex or red-dot optics without altering the pistol. With its crisp single-action trigger, ambidextrous thumb safety, and simple one-button takedown, this full-size .22 LR is a versatile choice for target work, training, or plinking.

The installed ADE Picatinny mini-rail lets you mount optics without gunsmithing, and it can be removed if you prefer the factory target sights. Ruger’s one-button takedown system on the Mark IV makes field-stripping quick and tool-free, a welcome upgrade over earlier generations.
The 5.5-inch alloy-steel bull barrel provides weight forward of the hand for steadier off-hand shooting and enhanced heat resistance during extended strings. Its blued finish matches the steel receiver for a classic look that complements the black polymer frame.
Target-style sights come standard: a Patridge front blade and a fully adjustable rear. Combined with the crisp single-action trigger and 1911-style grip angle, the pistol offers a familiar, confidence-inspiring feel for accurate shot placement.
Controls are user-friendly: an ambidextrous thumb safety, left-side push-button magazine release, and textured polymer grip panels with Ruger medallions that provide a secure, comfortable hold.
