The Ruger Mark IV Target .22LR Pistol was designed to fix a problem that has been frustrating shooters for decades. With it’s updated design the Mark IV now features a one-piece CNC machined grip frame that has a simple one-button takedown for quick and easy field-stripping and proper chamber to muzzle cleaning. The recessed button in the back of the frame allows the upper receiver to tilt up and off of the grip frame without the use of any tools. The Mark IV has an internal cylindrical bolt construction that ensures permanent sight to barrel alignment and higher accuracy potential than conventional moving-slide designs. Contoured ejection port and easy to grasp bolt ears allow for durable and reliable operation round after round. This gun also has an accurate sighting system that features an adjustable rear sight drilled and tapped receiver for weaver or Picatinny style rails.
