M4A1 GBB Assault Rifle Replica

The replica was made of steel, metal and high-quality polymer. Metal parts include the receiver of the replica, the stock slide, transport handle, front sight and the magazine. The pistol grip and handguard were made of polymer as well as the adjustable stock. Small elements such as pins, barrel rings, external barrel or the flash hider were made of steel.

The replica is powered by Green Gas, loaded directly into the magazine with a capacity of 30 BBs. Features an operational bolt-catch mechanism - when the last bullet leaves the replica, the lock remains in the rear position. Once a new magazine is loaded, bolt-catch release button must be pressed, which also puts the BB inside the chamber. It is possible to disengage this system via a switch in the magazine. This will enable the use of the replica as a safe, training weapon or a prop - it will be able to “dry” fire with an empty magazine whilst retaining all sound and visual effects provided by the GBBR system. 

An additional realism is boosted by a new system introduced by the manufacturer - the so-called Open Bolt. WE replicas with this solution do not feature a brass insert in the bolt chamber, which was present in earlier models from this manufacturer. Thanks to the implementation of this system, the entire bolt gets pulled backward during shooting, just like in the live version.

The set includes:

 - replica
 - magazine
 - key for assembly
 - BB speedloader

Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy).

Yes, adjustable
