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
Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting.
It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second).
1 FPS = 0,3 m/s
1 J = 99 m/s
1 J = 326,7 FPS
Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. 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).
