The replica"s main frame has been built with use of steel, used for making of the whole receiver, cover (together with the iron sights) and the butstock with its swivel, as well as some of the minor elements, such as the fire mode selector. Other metal elements have been amde out of the more classical alloy of zinc and aluminium. The pistol grip, and foregrip have been made out of high quality, durable plastic modelled in a way allowing it to nicely blend in as wood imitation and thus giving the replica an original look known from the real steel

The RK-01"s buttstock can be folded to the side, thus allowing to greatly decrease the replica"s length when so needed. The stick-type battery fits in under the dust cover. The replica can be partially taken apart in a way resembling it"s real steel counterpart. It"s hard to find any screw here, apart from just a few obvious ones, as the replica is based off the well-known and renowned VFC construction. On the side of the receiver, a dovetail-type mounting system can be found.

The replica is powered by a v3 type gearbox, well known for its high durability and ease of upgrading. Inside the geearbox, you will find a mushroom-shaped piston head, an reenforced spring guide with bearings and steel torques set onto 7 mm bearings. 

The replica is supplied with a plastic hi-cap magazine with a capacity of 500 rounds, a sling and a cleaning rod.
