An AEP from CYMA, the CM.136 is based on the MP433 Grach design and L'Antre Du Dingo got one to check out. CYMA made this AEP with a blowback feature by relocating the battery from the slide to the magazine. Mimicking a gas blowback gun (GBB), the user must rack the slide to fire, which recoils with each shot and locks back on empty. Interestingly, the gun can still function with a dead battery by manually reloading after each shot. The replica boasts a MOSFET system, improved wiring, a unique gearbox design, and durable polymer internals with steel gears for smooth operation.
