I like this product - SureFire Warcomp Flash Hider w/Suppressor Adapter

Required to work with the quick detach. Seems like I got the both of both worlds with the flash hider and muzzle brake. I have not shot it enough to really tell how the muzzle brake works but I believe it looks good. It works well with the quick detach of the Surefire suppressor line. I wish the instructions were a little better on how you determine which spacers to use. I pretty much just go by trial and error along with looking at the chart. The online videos of how to install the Warcomp are great. I watched them to make sure I was doing it correctly and they helped a lot.
