The Remington Model 572 Fieldmaster is a slide action, manually-operated .22 caliber (rimfire) rifle manufactured by Remington Arms Company. First introduced to the commercial market in 1956, the 572 Fieldmaster rifle incorporates a tubular magazine capable of feeding .22 Short, .22 Long, or .22 Long Rifle rimfire cartridges, a cross-bolt safety, and an aluminum receiver grooved for scope mounts. The original Fieldmaster used a 22.75-inch barrel. The Model 572 uses many of the design features first introduced on the Remington Model 870 shotgun, and replaced the Model 121 Fieldmaster as the company's slide-action rimfire repeater.
