a brushed aluminum receiver made to resemble stainless steel and 18.5" barrel with a black synthetic stock. Also offered in a black alloy receiver and 16.12" threaded barrel with a flash suppressor or with a threaded, fluted target barrel. 10/22 Takedown Lite The Takedown Lite models are similar to the other Takedown models but has a lightweight target barrel design. SR-22 Rifle In 2009, Ruger released the SR-22 Rifle model, a 10/22 receiver embedded in a chassis that mimics the dimensions of an AR-15 style rifle such as their own SR-556. The SR-22 Rifle uses standard 10/22 rotary magazines, in addition to most aftermarket 10/22 magazines. 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 Rifle competes directly with other AR-15 style rimfire rifles such as those made by Colt and Smith & Wesson. The SR-22 rifle boasts an aluminium handguard, adjustable six position stock, and a top receiver rail. Threaded holes on the handguard provide the customization of optional attachment rails. 22 Charger Pistol The 22 Charger pistol, first introduced in late 2007, is a pistol based on the 10/22 action. The 22 Charger originally came with a black laminated wood pistol stock with forend, a matte blued heavy barrel, a bipod, and a Weaver style scope base in lieu of iron sights. Overall length is just under , making it quite large for a handgun. As it has an included bipod it is likely to be used from a shooting bench or table. The bipod attaches to a sling swivel on the stock fore-end and is easily removable. Due to technical features, such as the magazine being outside the pistol grip, the Charger is not legally available in some U.S. states. The 22 Charger was later discontinued. It was reintroduced in December 2014, with a brown laminate stock with a M16A2 style pistol grip, 10-inch threaded barrel, picatinny rail, 15-round magazine and adjustable bipod. At the same time a "Takedown" model was introduced with a green laminate stock. Both models were later offered from September 2015 with black polymer stocks. 10/22 Magnum The 10/22 Magnum was produced from 1998–2006 and was chambered for the .22 Magnum cartridge. 10/17 The 10/17 was announced in 2004 and was chambered for the .17 HMR cartridge.
