Gas and Co2 Powered Airsoft Pistols, Choose either a gas or a CO2 powered Airsoft Gun from a fantastic range. Using compressed gas is the best way to pack loads of power into a small gun. All gas guns we stock have internal metal components and are green gas compatible. As a general rule you will get around 3 magazines worth of shots between refills. Our Co2 guns use small Co2 capsules which fit inside the magazine and as a rule will be slightly less powerful but you will get 150 - 250 shots per capsule depending on the power or if there is a blowback slide. You do not need to be a registered airsoft skirmisher to purchase from our range of airsoft guns but you must aged 18 or over. All of our airsoft guns comply with the VCR act 2007 and therefore will be transparent or brightly coloured in order to distinguish them from realistic imitation firearms.
