GBB Custom parts NPAS
RA-TECH NPAS Kit for Marui M4MWS・Type 89 GBB
This is a NPAS kit compatible with Tokyo Marui M4MWS(includes Block1)GBB、Type 89 GBB . This can be installed just by exchanging the piston valve with this NPAS.
This NPAS is used in our WE GBBs sold by ORGA. To adjust the amount of gas flow, please use the exclusive wrench included in this kit.
■The convenience of having a NPAS
During hot weather, when the gas pressure in the magazine increases, it can boost up the initial speed. Usually, the negative pressure valves could not be adjusted on the spot. However, this NPAS will allow you to adjust the initial speed with a single adjustment wrench.
■About NPAS
NPAS is a system installed in the bolt carrier that can change the flow rate to distribute the gas rising from the magazine to the initial speed side and the recoil side.
Usually, it is a type that swings to the recoil side, so that the amount of recoil blowback can be adjusted.
Please be assured that there is no extreme initial speed boost even if you swing it towards the side of the initial speed.
