A long-awaited line of replicas by Nuprol that was designing it for the last 3 years. The result is an impressive series of exceptionally original and carefully selected models of high quality, characteristic for replicas from a much higher price range.

Made from Aluminum, steel and high quality nylon polymer, the replica is characteristic for how well its parts fit together and excellent aesthetics of the craftsmanship. Structurally reinforced nylon used to manufacture the pistol grip and stock looks very good comparing to other products from other well-known and prized manufacturers – both visually and when it comes to durability to mechanical damage. Thanks to the implementation of QPQ painting technology it is incredibly resistant to scratching and chipping off.

Aluminum receiver and handguard were made using CNC technology, which guarantees that elements will fit well together. The replica is equipped with a 22 mm top RIS rail and an adjustable, telescopic SF stock. The battery is stored inside the stock. The RIS rail bears flip-up, adjustable, metal iron sights in an angled system. Such a solution allows for the attachment of chosen optoelectronic aiming devices without having to remove the iron sights. Standard flash hider is based on 14 mm left-hand thread, which allows the attachment of a silencer in its place. The handguard has a standard configuration of 4 RIS 22 mm mounting rails that enable the attachment of any accessories to the replica. Furthermore, the set includes a front grip that increases stability and ergonomics of the replica.

Elements of the same pneumatic system have also been made with highest care for details. The replica also features a QD quick spring change system that will help to adapt its power to the current conditions on the battlefield in the blink of an eye. A barrel with a diameter of 6.03 mm provides good cone of fire and repeatability of shots. A one-piece, polymer Hop-Up chamber is excellent – Hop-Up adjustment is done as in any other replica of the type – in order to gain access to the adjustment system it is necessary to pull back the charging handle. An operational bolt-catch is also worthy of note.

The reinforced, metal gearbox conceals steel gears and a piston with steel teeth. The entire mechanism is powered by a motor with increased torque. The replica is fully compatible with LiPo and LiFe batteries and is equipped with a Tamiya small connector.

The set does not include a battery or a charger.
