Red Army Airsoft reviews the G&G ESG B10, a gas-powered bullpup airsoft shotgun which they say resembles the Croatian VH6 rifle or the Airsoft Evolution FLAG 10. Designed for close-quarters combat (CQB), it has an effective range of approximately 15 meters, emphasizing a wide BB spread over long-range accuracy. The ESG B10 offers two firing modes—5 or 10 BBs per shot—controlled via a selectable switch and utilizes standard M4 AEG magazines, providing flexibility in magazine choices, including high-capacity options. Weighing 3.2 kg with a rear-biased center of gravity, the shotgun is constructed with a nylon body, steel components, and an aluminum alloy outer barrel. It features a Picatinny rail for optics, a carry handle, and QD sling slots. Its internal mechanism allows simultaneous firing of 5 or 10 BBs without a hop-up system. They demonstrate shot patterns using different BB weights and gases, highlighting its performance at close range, with a single gas fill lasting around 1000 BBs.
