A New Addition to the Family. Sturm, Ruger & Company, Inc. is adding three new models to the growing Ruger Mark IV family of rimfire pistols. Ruger has long set the standard for reliable, affordable and accurate .22 LR handguns, beginning with the introduction of the Standard Pistol in 1949. In 2017, Ruger proudly introduces a bronze anodized Mark IV 22/45 Lite model.

While the heavily redesigned Mark IV maintains the same classic outward appearance as the Mark III, it incorporates a significant improvement customers will love – a simple, one-button takedown for quick and easy field-stripping. 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. The bolt simply slides out of the receiver and the barrel can be properly cleaned from chamber to muzzle. Other new features that are common to the Mark IV family include an ambidextrous manual safety and a redesigned bolt stop for more ergonomic operation.

The Mark IV 22/45 Tactical combines a lightweight, precision-molded, polymer grip frame with a rugged steel upper receiver.

The Mark IV 22/45 Tactical also features adjustable target sights, an installed Picatinny rail for easy mounting of optics and a factory-threaded 1/2″-28 muzzles to accept popular muzzle accessories. The comfortable, precision-molded polymer grip frame incorporates replaceable Hogue black rubber grip panels that allow shooters to customize the look of the pistol. The Mark IV 22/45 Lite is the perfect outdoor companion and can be used for target shooting, plinking, small game hunting or competitive shooting.
