Key Features

Evolution Shotgun Bullpup-10

The ESG B-10 is G&G's first foray into creating a gas shotgun that additionally uses only AEG mags, allowing for greater user customization and flexibility.

Many of the features—easy to access gas valve, full ambidextrous, AEG mag compatibility—were meticulously researched and implemented to give you a pathway towards ease-of-access and upgradability.

GT Advanced branded products enjoy a 13-month Limited Warranty period from the date of purchase.
