Sometimes I think it is a shame that CO2 rifles do not get the credit they deserve. In many ways they offer the same advantages of a pre charged pneumatic (PCP) rifle without the cost and hassle of a dive bottle or pump system.
Take the SMK CR600W its lightweight, well balanced, recoilless, quiet and very affordable. Powered by one 12 gram CO2 capsule it packs a punch of around 9ft.lbs which is more than suitable for taking rat, pigeons and small vermin.
The rifle comes fitted with open sights and is supplied with a one shot tray and a seven shot magazine which is a nice touch.
I think this is a great little gun well suited to the back garden plinking, especially for lightly built shooters who do not want a heavy gun.
Ideal for vermin control or target, .177 & .22 calibre are available.
