Ruger Mark IV 22/45 .22 LR 5.5 in

The Ruger Mark IV 22/45 is a .22 LR semi-automatic pistol built for range work, training, and precision target shooting. Its design emphasizes easy maintenance and a stable sight-to-barrel relationship for consistent .22 LR performance.

The pistol features a one-button takedown that allows the upper receiver and barrel assembly to tilt up and off the grip frame for tool-free field-stripping and chamber-to-muzzle cleaning. Ergonomic controls and a checkered grip provide a secure hold, and the receiver is drilled and tapped to accept Weaver- or Picatinny-style optics mounting.
