High-Precision .22 LR Pistol with One-Button Takedown

The Ruger Mark IV 22/45 is a modern .22 LR pistol offering exceptional precision and reliability.

A contoured ejection port, easy-to-grasp bolt ears, and adjustable rear sight support smooth and consistent performance. The receiver is drilled and tapped for mounting optics using Weaver- or Picatinny-style rails.
