The first airsoft gun to be released by Tokyo Marui that is not based on any real world firearm, the Tokyo Marui SGR-12 is the second gun that uses the AES (Automatic Electric Shotgun) tech. The company announced that they are going to release the SGR-12 on the 4th of August 2017 and that means you better place your pre-orders at airsoft retailers that are going to have it in stock if you been eyeing this as your next airsoft shotgun.
