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.

Revolver is a repeating handgun that has a revolving cylinder containing multiple chambers and at least one barrel for firing. Revolvers might be regarded as a subset of pistols, or as an equal-ranking subset of handguns, distinct from pistols. Though the term "revolver" usually only refers to handguns, other firearms may also have a revolving chamber. These include some models of grenade launchers, shotguns, and rifles.Though the original name was revolving gun, the short-hand "revolver" is universally used. (Cannon using this mechanism are known as revolver cannon.) Nearly all early revolvers and many modern ones have six chambers in the cylinder, giving rise to the slang term six-shooter; however, revolvers with a number of different chambers have been made, with most modern revolvers having 5 or 6 chambers.
