Metal and glass fibre reinforced plastic were used to make the replica. The whole has been perfectly fitted. Metal was used for the body, front grip, external barrel, flask guide, mechanical sights and most of the small parts. On the other hand, the butt stock and pistol
grip are made of plastic. Exhaust device is made of steel.
The replica is equipped with a telescopic stock with space for a battery. The flask is adjustable, so you can adjust the length of the carbine to the build and preferences of the shooter. The pistol
grip has been contoured to ensure the best possible fit in the hand. The flame suppressor is mounted on a 14mm lefthand thread.
The replica is ideally suited for medium range operations, due to its discharge velocity of ~350 FPS. The applied dorsal RIS rail allows to attach any aiming optical device, while the multiposition, battery compartment allows to adjust the replica to individual user's preferences. The set includes a set of folding, mechanical flipup sights.
Apart from high quality parts typical for G&G, the GB has an innovative ETU (Electronic Trigger Unit) system installed. The system completely replaces the contact block and acts as a MOSFET type circuit. Thanks to the electronic trigger operation, the system has gained an excellent response to the trigger. Each press of the trigger results in a full GB cycle.
The ETU system has the possibility of programming the modes of conducting fire. The basic user has access to SAFE SEMI modes and a choice of FULL AUTO or 3shot burst. Programming is trivial just set the selector to SEMI position and hold the trigger for 10 seconds. After this procedure, on the third selector setting, the selected mode will be activated.
The replica has been designed for both right and lefthanded users. Manipulators such as: selector, magazine
release and reloading handle. This is a particularly useful solution in the case of games requiring the replica to be moved to the shooter's other arm.
The kit does not include a battery or charger.
