It almost sounds like you want a big flash out of the end at night the way you are askinf which one has the coolest flash. The flash supressors we are talking about do the opposite in case you were not aware of this. They pretty much get rid of all the flash so you cant see any flash at all. Now to me... that is cool! In any case; in testing we have done with the folloing flash suppressors, our results are as follows. Vortex and Phantom work very close to the same getting rid of almost ALL flash with numerous types of ammo. If there was a flash at all, it was a small poof, maybe golfball size. KKF A3 and standard A2 Birdcage suppressors work well, but not nearly as well as Vortex or Phantom. Flash out of these were more like a softball or small melon size. Compare this to flash with a crowned barrel which produced gigantic beach ball balls of flame that absolutely ruined everyone's night adapted eyes! I have a video of this, but no way to post it to the net...
