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.

It is a manually operated bolt action with two forward dual-opposed lugs. The bolt face is recessed, fully enclosing the base of the cartridge, The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body and bolt handle). The receiver is milled from round cross-section steel.

This rifle has a "turn-bolt" or "turn-pull" design, which involves the shooter doing an upward "turn" movement of the handle to unlock the bolt from the breech and cock the firing pin, followed by a rearward "pull" to open the breech, extract the spent cartridge case, then reverse the whole process to chamber the next cartridge and relock the breech. It features "Cock On Opening", meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin (there's a Cam mechanism pushing the Cocking Piece of the Firing Pin backward)
