The Tokyo Marui MWS is the benchmark M4 GBBR, and its one consistent weak point is magazine cost and weight — carrying four or five OEM mags is heavy and expensive. The Guns Modify EVO is the established aftermarket answer: a magazine engineered specifically for the MWS that cuts weight while matching or improving on OEM gas performance.
The V4 revision is the current generation, with reworked internal seals and a refined valve that improves gas efficiency and cold-weather consistency over earlier EVO versions. The result is a magazine that delivers its full 35-round capacity on a single gas fill in typical conditions, with consistent velocity from the first round to the last.
Weight reduction is the headline. The EVO shell uses a lighter construction than the OEM Marui magazine, which adds up significantly across a full loadout — four EVO mags noticeably lighten a rig compared to four OEM mags, without sacrificing the drop-resistance a skirmish mag needs.
Compatible specifically with the Tokyo Marui MWS system and the rifles built on it. Not compatible with VFC or other GBBR magazine patterns — this is an MWS-platform magazine. Verify your rifle is MWS-pattern before buying.
