G&G ESG B-10 Gas Non-Blowback Shotgun - Black

GNB Gas Shotgun ESG B-10 by G&G

ESG B-10 is a gas-powered shotgun designed as an effective cleaner for CQB games. With its bullpup design, it offers compact dimensions and easy handling, making it an ideal choice for moving from room to room. The upper body with RIS rail and handguard is CNC-machined aluminum, and the lower part is made of high-quality polymer, ensuring durability and long lifespan.
The shotgun supports shooting modes of 5 or 10 BBs per shot, making it akin to a small portable grenade launcher. The gas reservoir in the stock allows firing up to 6–7 magazines (approximately 100 BBs) per gas fill. The weapon is compatible with AEG M4/AR15 magazines, allowing you to use mid-cap magazines with higher capacity or even a drum magazine.
The gun is equipped with M-LOK and RIS rails, enabling easy mounting of accessories such as flashlights or lasers. The barrel features a 14-mm CCW thread for mounting tracer units or suppressors. A full RIS rail for red dot sights and fiber optic iron sights ensures precise aiming.
Controls are designed for both left- and right-handed users.
The main highlight is the Double Action mechanism, meaning there’s no need to manually cock the shotgun before each shot. Simply pull the trigger. A minor drawback is the lack of hop-up, resulting in an effective range of about 15 meters. However, it’s a CQB specialist designed for one purpose: enter and clear. With a few volleys of 10 BBs, no one will escape unscathed, and honestly, how many CQB arenas have rooms longer than 15 meters?
