Ruger Mark II Target .22 LR Stainless 5.5" Bull-Barrel Semi-Automatic Pistol
This stainless Ruger Mark II Target combines the proven straight-blowback action with a 5.5-inch bull barrel, giving shooters a steady sight picture and minimal recoil. Built in late 2000 (2001 model year) and among the final Mark II pistols before the line transitioned to the Mark III, it retains the original heel magazine release and lacks the later magazine disconnect and loaded-chamber indicator. All-stainless construction and target-grade adjustable sights make this full-size .22 LR a practical choice for competition, training, or collection.
