Randy the AKConcepts DNTC brake on an AR doesn't have much flash if using good ammo like American Eagle, M855 and such.
If using Guatamalan it has a HUGE flash. It's a very good comp and reduces recoil and muzzle lift very well, it is louder than an A2 comp but not as loud as a Cooley or my F2 comp.
Here's what it looks like with American Eagle (16" midlength bbl).
Here's with South African on DavidP14s Olympic M16 lower (w/H buffer) and our ARES piston converted 11.5" upper. This combo was VERY controllable, witht an aggressive stance I could keep the entire mag on full auto in a 1.5-2ft circle at 125-150yds without climbing off the target. It's cyclic rate was much slower than with Davids 10.5" LMT upper.
