A quick review by Strike Planet of the CYMA CM680G AEG that they have available at their store. It’s made of various materials including steel for the outer barrel, stock ring, and fasteners, nylon for the receiver, receiver cover, and DTK, plastic for the handguard, pistol grip, and stock, and metal for the stock tube. It weighs 2680g and has a length of 890mm to 970mm. The stem length is approximately 455mm. The device operates with an AK-type battery and a mini Tamiya connector, both of which are included along with a charger. The muzzle energy is less than 3J and the initial shot speed with a 0.2g BB is 130m/s. The model features a picatinny rail, M-LOK handguard, and a retractable stock.
