If you’re a fan of the Ruger Mark IV 22/45 Lite family of rimfire pistols, you’ll notice something a little different about its newest model. See it? Or rather, don't see it? That’s right. No Picatinny rail. In its place is a mounting position for a standard Shield RMS footprint reflex optic. It also features a raised front fiber-optic sight and an adjustable rear sight that co-witness with most micro red-dot optics. The new model has an attractive ventilated rib on top of a clear anodized receiver. 

Like most Ruger Mark IV 22/45 Lite pistols, the new model combines a lightweight, precision-molded, polymer grip frame with a ported, anodized aluminum receiver for a custom pistol look without the custom price. Chambered for the popular .22 LR cartridge, this pistol is fun to shoot, accurate and reliable. Weighing only 22.5 oz., the 22/45 Lite is an ideal lightweight rimfire pistol. The CNC-machined aluminum receiver houses a 4.4-inch stainless steel barrel, held in place by a tension nut to ensure accuracy and a factory-threaded 1/2"-28 muzzle to accept popular muzzle accessories. 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 one-button takedown, two 10-round magazines, and a 1911-style grip angle, it’s the perfect .22-cal. training pistol.
