The ESG B-10 2.0 Evolution Bullpup builds on the original ESG platform with a redesigned and more compact chassis intended to improve handling and manoeuvrability in close-quarters environments. With an overall length of just 470 mm, the platform delivers exceptional agility while maintaining the multi-shot shotgun functionality that defines the ESG series.

The shotgun uses a bullpup layout with an integrated green gas reservoir, allowing multiple magazines to be fired on a single gas fill without relying on gas-powered magazines. This design improves operational consistency while keeping the magazine system simple and widely compatible.

The ESG system fires 5 or 10 BBs per trigger pull from a single barrel, with the firing mode selected using the AEG-style selector switch. This allows players to quickly switch between tighter groupings or wider spread patterns depending on engagement distance.

Externally, the shotgun is built around a reinforced polymer bullpup chassis designed to reduce weight while maintaining structural rigidity. CNC-machined aluminium Picatinny rail sections provide durable mounting surfaces, while integrated M-LOK slots allow flexible accessory mounting.

The removable lower handguard exposes an additional Picatinny rail section suitable for vertical grips or other accessories. A full-length Picatinny flat-top rail allows the installation of optics or other sighting systems.

Weighing 2650 g, the ESG B-10 2.0 is noticeably lighter than the original platform, improving mobility while maintaining stability during firing.

Supplied with a 105-round GOM V2 mid-cap magazine, the ESG B-10 2.0 retains compatibility with standard M4 AEG magazines while delivering distinctive bullpup shotgun performance.
