The G&G CM16 Predator is a popular airsoft electric gun (AEG) known for its high-performance internal features and aggressive styling. It features an Electronic Trigger Unit (ETU) and a pre-installed MOSFET chip, which significantly improve performance and protect the electronics. 
 
Key Features
Integrated MOSFET & ETU: These components protect the system when using LiPo batteries (an 11.1V LiPo is often recommended for optimal performance) and provide a faster trigger response. The ETU can also be programmed to switch the full-auto firing mode to a 3-round burst.
Durable Construction: The body is made from a high-quality, lightweight yet durable polymer, while the unique KeyMod or M-LOK handguard is made of metal (CNC machined aluminum).
Ambidextrous Controls: The airsoft gun is designed to be friendly for both left- and right-handed users, featuring an ambidextrous magazine release and mock charging handle.
Aggressive Design: It has a unique billet-style receiver and a distinctive flash hider integrated into the rail system, giving it a modern and aggressive look.
Adjustable Stock: It comes with a six-position retractable GOS V3 stock that has an integrated battery compartment.
