Artemis CP2 Airgun/Pistol CO2 COMBO AIRGUN SET.
You can screw a silencer, attach a butt and change the barrel for a longer model to gain velocity and accuracy at long distance. Two rotating chargers are delivered in the kit, enough to have fun in the fields.
The CP2 pistol is pretty amazing. It is actually a platform, quality, which will accommodate the choice of a 21cm gun or another 44cm. A silencer can be screwed at the end of the two guns. The CO2 cartridge fix into the cylinder under the barrel.
The airgun can be converted into a rifle by removing the base of the handle. A screw, provided with a movable ring allows to remove the base and to fix the removable butt of the Airguns.
