This might not exactly a very stealthy custom AEG done by Black Ops Airsoft but it sure is still a very cool work for us... "Hello! A customer from Connecticut saw our previous customization work and was a huge fan of it. He gave us a call and asked for us to install an ECHO1 zombat flashhider and an electro-luminescent system onto his KWA M4. Check it out! Feel free to share. You saw it first here at Black Ops Airsoft!"
