The Mark III Target configuration centers on a 5.5 inch bull barrel for steady sight tracking and consistent balance. The steel upper receiver is finished in blue, while the bolt is left in-the-white, creating the classic Mark III two-tone functional look. The receiver is drilled and tapped for a scope base, and the filler screws are installed.
Target-focused sights come standard: a fixed square-post (Partridge) front paired with a fully adjustable rear. The iron sight picture is clean and repeatable, and the right-side ejection port complements the platform’s straightforward operation.
The 22/45 polymer grip frame in the RP (replaceable panel) configuration is fitted with checkered cocobolo wood panels bearing Ruger medallions. Controls include a push-button magazine release, a manual thumb safety, a magazine disconnect, and a loaded chamber indicator. The single-action blowback system and single-action trigger deliver a familiar Mark III feel.
