The G&G ESG B‑10 delivers rapid multi-shot firepower in a compact bullpup gas shotgun design. Compatible with standard M4-style AEG magazines, it offers selectable 5- or 10-round burst firing modes—combining flexibility, modularity, and CQB-centric impact.

Product Features:

• Innovative bullpup layout with internal gas reservoir and lightweight polymer/aluminium construction
• Selectable 5-shot or 10-shot burst mode per trigger pull, driven by the AEG-style selector switch
• Uses standard M4 / AR‑15 AEG magazines, including the supplied 105-round mid-cap GOM V2 mag
• Ambidextrous controls and dual QD sling points accommodate both left- and right-handed users
• Full-length Picatinny top and bottom rails, plus M-LOK slots at 3 and 6 o’clock positions for accessories
• 14mm CCW threaded outer barrel supports tracer units or suppressors
• Full-auto-style versatility powered by green gas

The G&G ESG B‑10 (Evolution Shotgun Bullpup‑10) redefines airsoft shotgun design by pairing a bullpup gas system with compatibility for widely accessible M4 / AR‑15 standard magazines. This semi-auto design fires either 5 or 10 BBs per trigger pull, selectable through the standard selector switch—eliminating the need for separate shot count variants.

Constructed from a blend of polymer and aluminium, the ESG B‑10 offers a robust yet lightweight layout. Weighing around 3.0–3.14 kg with a total length of approximately 560 mm, it’s designed for maximum manoeuvrability in CQB environments.

Externally, the ESG B‑10 includes top and bottom Picatinny rails, as well as accessible M-LOK slots at 3 and 6 o’clock, allowing wide accessory options. Controls remain fully ambidextrous, including sling points, mirroring the high flexibility expected in modern multi-role builds.

One of the ESG B‑10’s standout features is its use of standard AEG mags, with the rifle supplied alongside a 105-round GOM V2 mid-cap magazine. G&G reports that a single gas fill can deliver 6 to 7 full magazines, thanks to the internal green gas reservoir positioned in the buttstock.

With its 14mm CCW threaded barrel, users can easily attach tracer units such as G&G’s own MF106T or UVT106. Shot performance in 5-shot mode delivers around 300FPS (0.20g), while 10-shot bursts offer significant spread—ideal for room clearing within a typical 10–15m effective range.

This field-ready gas shotgun is unmatched in versatility—allowing players to leverage standard AEG magazines, modular rail systems, and selectable burst-fire options in a streamlined, competitive package.
