The AK series of guns are one of the baddest and rugged guns around since its first appearance in 1947 as the famous AK47. Now take that same assault rifle and turn it into a full and lightweight machine gun, you have the RPK. It featuring an all metal construction which includes metal receiver, receiver cover, cover retainer button, trigger, trigger guard, magazine release, magazine, bolt and charging handle, mock gas piston, fire selector lever, rear sight, gas tube release lever, front sight block, and its threaded outer barrel. The rear sight is adjustable and hop-up adjustment can still be performed by simply pulling back on the bolt cover. An added feature on the RPK is a metal Bi-pod that can be folded away with a twist.

Housed within is a enhanced Version 3 full metal gearboxes that now shoots 400-450 FPS, one of the hardest shooting guns available on the market. It is a work horse of a design that includes high durability gears, a high torque motor, and a M120 spring running the show. Finished with real wood furniture on the hand-guards and its full length RPK style stock that takes large type batteries, this gun is a masterpiece in power, performance, looks, and realism. To top it off it includes a long enduring 800 round long magazine for when you have to lay down a lot of rounds on your enemies.
