Remington Model 512 Sportsmaster

The Remington Model 512 Sportmaster is a bolt-action rifle manufactured by Remington Arms.^[1] The Model 512 has a 25-inch (64 cm) barrel, a one-piece hardwood stock, and a blued metal finish.^[2] An unusual feature of this rifle is that it uses a tubular magazine in conjunction with a bolt action. Most modern tube-fed firearms typically use a lever action or a pump action, but in the middle of the 20th century, many bolt-action .22's used tubular magazines as the high-capacity magazine of the era.^{[citation needed]}
