  • Realistic flash and muzzle gasses - Awesome!

If you love realism and will do anything to get closer to the real thing, the HASTA NEBULA Tactical Mist Tracer Unit belongs on your primary. The first of its kind in the world, this tracer unit not only provides muzzle flash, rainbow muzzle flash and tracer functionality but also provides realistic simulated muzzle gasses with each shot. With slick new functionality comes the need for intel, so make sure you thoroughly read the "Special Instructions" section of the full product description before ordering!

The mist generation function runs off a water-glycol solution, just like smoke machines used in film and TV production and the internal fan gently blows the simulated muzzle gas out of the front of the suppressor each time a BB passes through. Powered by an internal rechargeable LiPo battery and charged via Micro-USB, the NEBULA is a seriously groundbreaking piece of Airsoft technology and we are proud to be the first to offer it to Airsofters!
