CYMA CGS / MWS / Hi-Capa GBB Magazine Output Valve

If you've got some old MWS, CGS or Hi-Capa mags to refurbish, the CYMA CGS / MWS / Hi-Capa GBB Magazine Output Valve is what you need! This set is a complete replacement original knocker valve (aka output valve), the valve at the top of the magazine which is struck by the valve knocker. Compatibility-wise, this should fit Tokyo Marui MWS ZET System Mags, CYMA CGS GBBR magazines, Tokyo Marui Hi-Capa mags and some TM clone Hi-Capa magazines (though this is not guaranteed). Whether you like to keep spares on hand so you're always battle-ready or your mags are a bit tired and need a revamp, the CYMA CGS / MWS / Hi-Capa GBB Magazine Output Valve will do the trick!
