The Guns Modify EVO Gas Magazine delivers innovative performance for Tokyo Marui MWS and compatible airsoft platforms. Its revolutionary core & case design allows quick field reloads—simply open the butt plate and press the internal button to slide the core free. The polymer case houses a durable metal core, engineered for reliable gas blowback operation. Out of the box, the core slides stiffly, so applying silicone oil to the exterior ensures smooth extraction and reloading.
