G&G ESG B-10 – Gas Bullpup Platform

The G&G ESG B-10 Gas Airsoft Shotgun delivers high-impact CQB performance in a compact bullpup design, combining shotgun-style multi-BB fire with the flexibility of standard M4 / AR-15 AEG magazines. Designed for aggressive close-quarters play, it offers selectable 5-shot or 10-shot burst modes per trigger pull, controlled via a standard selector switch.

Built from a lightweight polymer and aluminium construction, the ESG B-10 remains highly manoeuvrable while maintaining durability. The bullpup layout keeps the overall length short—approximately 560mm—making it ideal for tight indoor environments, doorways, and fast transitions.

Powered by green gas, the ESG B-10 features an internal gas reservoir housed in the buttstock, capable of delivering 6–7 full magazine loads per fill. Shot performance sits around 300 FPS (0.20g) in 5-shot mode, while 10-shot bursts deliver devastating spread for effective room clearing within 10–15 metres.

Externally, the shotgun is fully modular, featuring full-length Picatinny rails on the top and bottom, plus M-LOK slots at 3 and 6 o’clock for torches, grips, and accessories. Ambidextrous controls and dual QD sling points ensure comfortable handling for both left- and right-handed users.

Supplied with a 105-round GOM V2 mid-cap magazine, the ESG B-10 is compatible with most standard M4 AEG magazines—offering unmatched convenience and loadout flexibility.

Performance & Build Quality

Its selector-controlled burst system eliminates the need for multiple variants, while the robust internal gas system delivers consistent output and impressive efficiency.
