A long video review of the A&K PKM AEG by Airsoft-RUS which has this available at their store. This replica of the Kalashnikov Concern-licensed PKM machine gun features a steel and aluminum alloy body with plastic fittings, automatic-only fire mode, and bipods. It includes a battery-powered 5000-round electric hopper magazine housed in a cartridge box, standard iron sights, a proprietary aluminum alloy gearbox with generally compatible internal components, and a unique hop-up chamber. Capable of using high-current 7.4V LiPo batteries (stored in the cartridge box with a Mini-Tamiya connector), it offers a programmable fire slowdown function and delivers an initial velocity of 120-130 m/s and a 750 RPM rate of fire with the included battery, weighing 7.2 kg fully loaded.
