The Ruger Mark IV Target pistol in .22 LR with a blued finish (brand part no. 40183) is a rimfire target pistol built around a simple one-button takedown for quick and easy field-stripping and proper chamber-to-muzzle cleaning. Ruger fits the pistol with a cold hammer-forged 5.5-inch bull barrel for ultra-precise rifling and exceptional accuracy, and internal cylindrical bolt construction ensures permanent sight-to-barrel alignment. A drilled and tapped receiver accepts a Weaver- or Picatinny-style rail for mounting optics, and an ambidextrous manual safety, a push-button magazine release, and a magazine disconnect round out the controls. Among rimfire target semi-auto handguns, this Mark IV configuration favors shooters who want precision plinking and target performance.
