There are two general types of cal. .22 rimfire rifles in use-the precision target rifle and the sporting rifle.
The Ruger Model 10/22 semi-automatic carbine is in the latter class. Chambered for the .22 long rifle cartridge, regular or high velocity, it is designed for small-game hunting and informal target shooting.
Action is of blowback-operated type, fed by a unique 1 0-shot detachable rotary magazine. In blowback-operated arms, the bolt is held shut by its inertia and pressure of closing spring. In the Ruger Model 10122 carbine, hammer pressure against rear of bolt also retards opening of the breech.
An AR-15 style rifle is a lightweight semi-automatic rifle based on the ArmaLite AR-15 design, which is itself a scaled-down derivative of Eugene Stoner's AR-10 design. ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959.
After Colt's patentsexpired in 1977, Colt retained the trademark and is the exclusive owner of the "AR-15" designation. The Public Safety and Recreational Firearms Use Protection Act restricted the Colt AR-15 and some derivatives from 1994 to 2004, although it did not affect rifles with fewer features.
