A good look at the CYMA CM.136 MP-443 Grach Airsoft AEP in this review by Mach Sakai. He discusses the AEP's design, ergonomics, controls, performance, and electric blowback. Key features include its unique look with a silver outer barrel, a grip that is surprisingly easy to hold, and a satisfying shooting feel that is closer to a gas blowback model. He notes the pistol for being very accurate with consistent muzzle velocities and demonstrates how to field strip it.

A quick look by Taiwan Gun of the CYMA CM.136 EBB MOSFET Edition they distribute in Europe. The CM.136 is the first AEP (Automatic Electric Pistol) with an electric blowback system. This is achieved by relocating the battery from the slide to the magazine. The blowback system mimics a Gas Blowback Pistol (GBB), requiring the slide to be racked before firing and cycling with each shot.

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.
