Ruger Mark IV 22/45 semi-automatic pistol in .22 LR with a 5.50″ bull barrel, blued finish and two 10-round magazines. Drilled and tapped receiver with adjustable rear sight; checkered synthetic grips.
The Ruger Mark IV 22/45 is a rimfire, semi-automatic pistol built around a 5.50-inch bull barrel and a checkered synthetic grip frame. It includes two 10-round magazines, an adjustable rear sight, a fixed front sight, and a drilled-and-tapped receiver for Weaver/Picatinny-style optics. For a practical optic under $1,000 that pairs well with this platform, consider a compact red-dot such as the Vortex Venom or Holosun 507 family for fast sight acquisition on the range.
Well-suited to precision rimfire target work and recreational plinking, the Mark IV 22/45 also serves for informal rimfire competition and small-bore skill development.
