Description

This is a classic Remington Sportmaster Model 512 bolt-action rimfire rifle, a popular sporting and training rifle produced primarily between 1940 and 1964. The rifle is chambered for the versatile .22 S, L, or LR (Short, Long, or Long Rifle) caliber. It features a blued steel barrel and receiver paired with a dark brown varnished wooden stock. The rifle utilizes a full-length tubular magazine located beneath the barrel, designed for high capacity. Key features include the knurled cocking piece on the bolt, a round bolt handle knob, an adjustable ramp rear sight, and a fixed front blade sight. The barrel is clearly marked with the manufacturer name “Remington,” the registered brand “SPORTMASTER ®,” the “MODEL 512,” and the caliber designation: “22 SHORT, LONG, OR LONG RIFLE.” Additional markings include “MADE IN U.S.A.” and visible patent numbers 2,356,257 and 2,369,244. The buttplate is a black, checkered hard rubber or plastic component bearing the Remington brand logo. (No measurements available.)
