Up for sale is a madbull xm-204hp 40mm shower shell. These shells are the best money can buy and retail for £75 + when purchased brand new. when you buy madbull shells you are paying for the quality of the machining work that goes into the shells production. This is why these shells are able to work reliably with high pressure gases like co2 and HPA and dont let you down like so many cheaply made alternatives. These shells rely shine when using co2 and provide excellent range even in the winter months, but they can also be used with HPA (must be regulated) green gas or propain. The shell is supplied gas tight and ready to rock and will also cone with some spare o rings for the internal valve core so if you do blow a seal you can be back in the game in under 3 minuits.
