Keeping your gas gun running clean and properly has never been easier now that ASG came up with the ULTRAIR Co2 Care Kit. This kit contains 9 normal 12g Co2 cartridges and 1 specially lubricated Co2 cartridge. The specially lubricated Co2 cartridge can be used like any other Co2 cartridge in your airsoft gun, but will automatically disperse a cleaning liquid throughout your gun when fired; keeping the seals, gaskets, and valves lubricated and functioning properly. Using the ULTRAIR Co2 Care Kit eliminates the need to buy extra cleaning materials and manually maintain your rifle between skirmishes. Keep your gas airsoft gun in tip top shape for when you need it the most, and pick yourself up the ULTRAIR 12g Co2 Care Kit from ASG today.
