Ruger 43921 Mark IV 22/45 Lite 22 LR 4.40" 10+1

The Mark IV features a simple, one-button takedown for quick and easy field-stripping and proper chamber-to-muzzle cleaning. Cold hammer-forged barrel results in ultra-precise rifling that provides exceptional accuracy and longevity. Internal cylindrical bolt construction 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. Accurate sighting system features a drilled and tapped receiver for Weaver- or Picatinny-style rail for easy mounting of optics. Ambidextrous manual safety can be converted to left-side only with included washer. Features a conveniently located push-button magazine release on the left side of the frame. Pressing a button in the back of the frame allows the barrel-receiver assembly to tilt up and off the grip frame without the use of tools. This 22/45 Lite model features an aerospace-grade aluminum, ventilated receiver with a diamond gray anodized finish. It also has a 4.4" barrel, black polymer grip frame, laminate wood target grip, and a fixed front sight with an adjustable rear.
