Product information
The G&G ESG B-10 is a compact gas-powered bullpup shotgun with semi-automatic operation and selectable five-BB or ten-BB firing modes. It uses a 200 mm 6.05 mm inner barrel and a 105-round magazine, with the gas reservoir integrated into the platform rather than a removable shell.
The ESG B-10 measures about 560 mm overall and weighs roughly 3.14 kg. G&G combines CNC-machined aluminium upper components with a high-density polymer lower, and the factory specification does not use an adjustable hop-up.

Published figures are a reference, not your replica’s chrono result. Equivalent speeds assume the same energy; changing BB weight can change measured energy. Check your own readings and your field’s limits.

Magazine notes
Uses standard M4 / AR-15 AEG magazines; G&G-branded magazines are recommended by the current UK retailer.
A shared pattern or interface helps narrow your search; it does not guarantee fit across every brand or revision. Follow model-specific notes.
