Ruger Introduces New Ruger Mark IV 22/45 Lite Optic-Ready with Co-Witness Sights

Sturm, Ruger & Company, Inc. (NYSE: RGR) has expanded the Ruger® Mark IV™ 22/45™ Lite family of rimfire pistols with a new model featuring a mounting position for a Shield™ footprint reflex optic. Standard RMS in place of the Picatinny rail. It also features a raised front fiber optic sight and adjustable rear sight that is a match for most micro red dot optics. The new model has an attractive vented rib on top of a clear anodized receiver.

Like most Ruger Mark IV 22/45 Lite pistols, the new model combines a precision-molded, lightweight polymer grip frame with a ported, anodized aluminum receiver for a custom pistol look without the custom price tag. Chambered for the popular .22 LR cartridge, this pistol is fun to shoot, accurate and reliable. Weighing just 22.5 ounces, the 22/45 Lite is the ideal lightweight rimfire pistol. The CNC-machined aluminum receiver houses a 4.4-inch stainless steel barrel, held by a tension nut to ensure accuracy, and a 1/2″-28 factory-threaded muzzle to accept popular muzzle attachments. The comfortable, precision-molded polymer grip frame incorporates replaceable checkered 1911-style 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. With a one-button detach, dual 10-round magazines, and a 1911-style grip angle, it’s the perfect .22 caliber training pistol.
