A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls.The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon.
An Armalite rifle (AR) is one of a series of rifles the ArmaLite company made or, more generally, a rifle based on one of its designs, such as the ArmaLite AR-15 rifle. Eugene Stoner , Jacques Michault, Melvin Johnson , Robert Fremont, and Jim Sullivan are some of the designers credited with their development. [ 1 ]
Others are designed for civilian hunting and sport shooting, which generally sell very well in countries such as the U.S. and Canada. Many of those produced have been destroyed, deactivated or fallen into disrepair, but others will have been kept in working order and sold or passed on from one generation to another down the years.
Revolving rifles were an attempt to increase the rate of fire of rifles by combining them with the revolving firing mechanism that had been developed earlier for revolving pistols. Colt began experimenting with revolving rifles in the early-19th century, and other manufacturers like Remington later experimented with them as well.

Most rifle cartridges have a high load density with the appropriate powders. Rifle cartridges tend to be bottlenecked, with a wide base narrowing down to a smaller diameter, to hold a light, high-velocity bullet. These cases are designed to hold a large charge of low-density powder, for an even broader pressure curve than a magnum pistol cartridge.
