This service will turn your standard Cyma spring shotgun into a semi-automatic beast, powered by a refillable internal CO2 cylinder hidden neatly in the magazine tube. Look ma, no hose!
We will only perform this operation on full-length magazine-tube shotguns, for example CM370/CM373, due to the size of the CO2 cylinder we can fit. A smaller cylinder would simply give an inadequate number of shots for useful gameplay.
The internal cylinder is quickly filled using a CO2 charger: simply unscrew the mag tube cap to reveal the filling valve. Each full charge will give around 60 shots (emptying 6×30rnd magazine shells).
The system is best recharged with 88g capsules, with each cartridge providing several refills, allowing you to fire a total of around 250 shots (emptying 25×30rnd magazine shells, firing a total of 750 BBs). So, it’s reasonably hungry for CO2 and can’t fire endlessly, like the HPA version. However, the experience is more realistic with no hose and much better suited to the shotgun being used alongside other weapons. Definitely the choice for MilSim players.
Like our HPA conversion, the system requires a small 11.1v Lipo battery to operate and will give around 260fps with 0.28g BBs.
This conversion will usually take 2 weeks to complete, but please contact us for current lead times.
