Ruger Mark IV Tactical 22/45 Semi-Auto .22LR 4.4″ Handgun

Simple, one-button takedown for quick and easy field-stripping and proper chamber to muzzle cleaning. A 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 tools. Ergonomic bolt stop. 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 adjustable rear sight and drilled and tapped receiver for Weaver- or Picatinny-style rail for easy mounting of optics. Ambidextrous manual safety positively locks the sear in the “SAFE” position when applied. Safety can be converted to the left-side only with the included washer. Features a conveniently located push-button magazine release on the left side of the frame. Magazine drops free on release for faster reloading. Magazine disconnect prevents discharge when the magazine has been removed. Threaded barrel and top and bottom Picatinny rails for attaching tactical accessories.
