The Remington Model 700 is a series of bolt-action rifles manufactured by Remington Arms since 1962. All are based on the same centerfire bolt action. They often come with a 3-, 4- or 5-round internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are "blind" (with no floor-plate). The rifle can also be ordered with a detachable box magazine. The Model 700 is available in many different stock, barrel and caliber configurations. It is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.
