In this part 2 video, El Bridos 5.95 details his challenging project to significantly reduce the noise of a CYMA Platinum AEG for airsoft. Initially aiming for a simple guide, he's found achieving a balance between performance and sound reduction complex. His modifications, including a Begadi motor, EPES cylinder head, and sorbopad, aim to alter the AEG's sound signature, making it harder to locate, rather than replicating an HPA system. He will continue testing and sharing his progress in future videos.
