CYMA CGS Tokyo Marui MWS Gas Magazine (30 Rounds) The CYMA CGS (Cyma Gas System) STANAG magazine is a versatile, modern alternative to the original Tokyo Marui MWS magazines. Built to interface with the ZET System , this magazine introduces a few innovative quality-of-life features—specifically the hybrid gas/HPA functionality and a unique internal feeding design—that make it a pragmatic choice for both skirmishers and tech-oriented players. Key Performance Features MWS ZET System Compatibility: Fully compatible with the Tokyo Marui MWS M4, MTR-16, and other AR-15 GBB platforms using the TM system. It mimics the dimensions of a standard 5.56 NATO STANAG magazine. Hybrid Gas/HPA Design: Standout among its peers, this magazine is designed with an optional HPA inlet port . This allows users to easily transition from Green Gas to a tethered HPA (High-Pressure Air) setup for consistent FPS regardless of temperature, without needing to permanently modify the magazine. Quick Detachable (QD) BB Tube: The internal BB track is designed as a detachable unit. This makes cleaning out dirt or debris—which can often cause feeding issues in gas magazines—significantly easier than the standard "clamshell" or "pinned" designs. Full Metal Construction: At 0.39kg (390g) , it has a realistic weight that provides a solid feel during reloads and helps the magazine drop free from the magwell efficiently. 30-Round Real-Cap: Maintains the realistic 30-round capacity favored by Mil-Sim players, ensuring that the manual of arms remains authentic to the real AR-15 platform.
