Remington 512 Sportmaster 512-X 22 LR 24" Bolt-Action Rimfire Rifle

The Remington Model 512-X Sportmaster is a classic, vintage bolt-action rimfire rifle featuring a 24-inch steel barrel. While the original standard 512 series featured a 25-inch barrel, this specific 24-inch variant defines the modernized and highly collectible 512-X iteration produced briefly between 1964 and 1966. The combination of a bolt action with a tubular magazine is a unique and defining feature of the Sportmaster series. During the mid-20th century, this setup provided a high-capacity option for a rigid and inherently accurate bolt-action platform, whereas most high-capacity tube-fed rimfires utilized lever or pump actions.
