The Ruger 10/22 Air Rifle has been a perennial best seller for 55 years. It's only fitting to offer shooters a CO2 powered repeating air rifle version of this iconic rimfire. The Ruger 10/22 Air Rifle uses two 12g CO2 cartridges to launch .177 caliber pellets from its 10 shot rotary magazine. Its magazine drops free from the rifle in authentic fashion and holds a 10-shot rotary magazine. Additional rotary magazines are available as an accessory. The receiver is tapped for the addition of an aftermarket rail made for the 10/22 making it easy to add a red dot or rifle scope. You can shoot the 10/22 Air Rifle in double action or single action. The single action trigger is very nice at about 4 lb of pull. Not only does the 10/22 Air Rifle look like the Ruger 10/22, it gives the air gun enthusiast the complete 10/22 experience with the quietness and convenience of CO2 power.
