In 2009, Ruger released the SR-22 model, a 10/22 receiver embedded in a frame that mimics the dimensions of an AR-15 rifle. The SR-22 uses standard 10/22 magazines, as opposed to the over-sized magazines used by most AR-15-style rimfire rifles. The positions of the magazine release, the safety and the charging handle are all more similar to a standard 10/22 than an AR-15. The SR-22 competes directly with other AR-15-like rimfire rifles such as those made by Colt and Smith & Wesson.

North American Arms model NAA22S mini-revolver, chambered in .22 Short.
Examples of revolver mouseguns include the North American Arms Mini Revolver, which is a spur trigger design with birdshead grips. The North American Arms Mini Revolver is styled very much like popular pocket revolvers of the 19th Century, but is made entirely of stainless steel.
Smith & Wesson’s “J-Frame” series of revolvers are a common choice for mouseguns. They are generally more reliable than their automatic counterparts, and offer an exceptional power-to-weight ratio, especially the lightweight AirLite and Airweight lines. On the other hand, they offer only five shots (auto mouseguns often hold more rounds), and have considerably greater recoil, especially in .357 magnum.
