RK104 ETU Crane - Tan

A replica manufactured by G&G belonging to a GT Advanced series, which is characteristic for its very good quality craftsmanship - both on the inside and outside. This allowed it to imitate the live firearm original as closely as possible, also in terms of size and construction details. Steel parts include the rear sight base, front sight base and dust cover. The pistol grip, stock and handguard were made from a very durable polymer.

Access to the hop-up chamber is gained in a traditional way - after pulling back the charging handle. On the right side of the receiver there is a winged fire mode selector and a safety.

The heart of the replica constitutes a GB V3, which together with 290mm long barrel allows to achieve a muzzle velocity of ~430 FPS and very good accuracy. The replica also features an E.T.U. trigger mechanism and MOSFET module that allows to reprogram the automatic fire mode into a burst mode. This is conducted by holding the trigger for longer than 10 seconds when the fire mode selector is set to semi fire.

The battery is stored inside the telescopic stock of the replica.

The replica comes with an artificial metal Hi-Cap magazine with a capacity of 450 BBs.

The set includes:
- replica
- magazine
- User’s manual
