G&G ESG B-10 Gas Shotgun

The headline trick of the ESG B-10 is the magazine system. Most multi-shot airsoft shotguns rely on proprietary gas shells that are expensive, slow to reload, and the first thing to break. G&G threw that out and built a gun that feeds from the same M4 AEG magazines you almost certainly already own — hi-cap, mid-cap, drum, anything. A 105-round mag ships in the box, and a single fill of the internal gas reservoir clears six or seven of them before you need to top up. For a shotgun, that's an enormous improvement over the old TM M870 that defined the category for years.

The selector lets you choose between 5-round and 10-round burst per trigger pull — five for tighter spread and BB economy, ten when you need to fill a doorway. Both modes deliver around 250 FPS on 0.20g BBs, with the wide spread that makes a shotgun a shotgun. The bullpup layout puts a 200mm inner barrel inside a 560mm overall length, so it handles like a stubby PDW rather than a full-size pump-action. M-LOK at 3 and 9 o'clock plus a 245mm-long picatinny carry handle give you proper modern rail real estate, and the 14mm CCW thread accepts any tracer unit you'd want for night CQB.
