The G&G ESB B-10 gas airsoft shotgun stands for Evolution Shot Gun Bullpup -10. The ESB B-10 is a gas-operated, semi-automatic shotgun that uses standard M4/AR15 magazines. You can choose either 5 or 10 shots per trigger pull with the M4/AR-15 style fire selector, rather than having to buy two nearly identical airsoft guns to achieve the same effect. This is a CQB airsoft gun, as the spread pattern on this airsoft shotgun is very wide, especially on the 10-round setting, so you could potentially clear rooms with just one shot.

The G&G ESB B-10 is a bullpup design and is also quite modular, as the ESB features a Picatinny rail on top and a Picatinny rail on the bottom, while there are M-LOK slots at the 3 and 6 o'clock positions. All of the ESB's controls are ambidextrous, even the QD sling attachments are present on both sides of this airsoft shotgun.

GreenGas and BBs are still required for operation.
