Surely ACM manufacturers will move fast to copy any innovation from other airsoft manufacturers. The latest to be copied is now the TM Xtreme Hi-Capa full auto gas blowback pistol which is really a fast shooting one. The copy is available at Gunner Airsoft and available for US$55.00 and this will fit existing TM Hi-capa mags being an exact copy. Just hope then when firing it the slide doesn't fly out due to the extreme blowback action.
