ARP556 Assault Rifle Replica
At first glance, the replica resembles a replica from the AR-15 series, but apart from the use of the Gearbox in version 2 or the pistol grip, the similarities end there. The ARP556 is a solid, compact PDW type replica. Unlike a similar ARP9 replica of the Combat Machine series, the ARP556 is made almost entirely out of metal. The replica is equipped with a folding stock made out of steel and plastic, the guide has a plug for the battery (not included) and a mosfet system. The replica uses a custom pistol grip, trigger and a metal M-LOK® rail with license markings. Folding sights were placed on the back of the replica. In addition to a strong polymer, the replica has steel elements, including: certain stock elements, the shell ejector flap that is opened with the enlarged charging handle, as well as the screws and pins. The barrel of the replica is topped off with a custom muzzle device. The replica comes with a hi-cap magazine with a capacity of 450 BBs.
In addition to the high-quality components typical for G&G, GB has an innovative ETU (Electronic Trigger Unit) system installed. The system complements the role of the MOSFET system. Thanks to the electronic operating system, the trigger has an excellent response time. Each press of it results in the performance of the full GB cycle. 
The ETU system can programmed to fire in a few modes. The user has access to the SAFE - SEMI - modes and a choice of FULL AUTO or 3 shots. Programming is very easy - just set the selector to SEMI and hold the trigger for 10 seconds. After this procedure, the selected mode will start on the third setting of the selector.
