G&G ESG B-10 Gas Multi-Shot Bullpup Shotgun (Black)
Redefining close-quarters capabilities, the G&G ESG B-10 (Evolution Shotgun Bullpup-10) combines semi-automatic gas operation, a compact bullpup platform, and standard M4/AR-15 magazine compatibility. Engineered for maximum room-clearing efficiency, it features a selectable multi-burst system that fires 5 or 10 BBs per trigger pull.
Key Features
-
Selectable Multi-Shot Firing: Easily switch between 5-shot and 10-shot burst modes per trigger pull for maximum suppression in tight CQB environments.
-
M4 / AR-15 Magazine Compatibility: Powered by standard M4 AEG magazines rather than traditional shells, letting you use high-capacity or mid-cap M4 mags.
-
Compact Bullpup Layout: Places the action and magazine behind the grip, concentrating weight in the stock for fast target transition and tight maneuverability.
-
High-Capacity Internal Gas Reservoir: Built-in buttstock gas tank allows hundreds of shots per single gas fill and can be adapted to HPA setups.
-
Fully Ambidextrous Controls: Features ambidextrous fire selectors, magazine releases, charging handles, and QD sling attachment points.
-
Modular Mounting System: Fixed aluminum carry handle with top Picatinny rail, bottom rail, and integrated M-LOK slots at the 3 and 6 o'clock positions.
-
14mm CCW Threaded Barrel: Single-barrel output allows standard airsoft tracer units or suppressors to illuminate or muzzle flash all outgoing BBs simultaneously.
