Bruce has his hands on the newest tracer unit with muzzle flash generator, the Acetech Blaster, for this BB2K Airsoft... "With the Acetech #BLASTER​ Tracer Unit you not only have a tracer on your airsoft, but also a muzzle flash generator. The simulation of the muzzle flash looks really awesome depending on the airsoft used. Gas blowback weapons of course have their big advantage here. The combination of gas cloud and LEDs is just awesome. The more gas goes out the more spectacular the whole thing looks. I will test a few GBB Airsoft for you in my review. Of course I will also go into all the functions of the blaster. Thanks go out to the company Acetech, who have provided me with their product sample so that I can show you the blaster."
