AAC is bringing a new flash suppressing compensator to market called the Brakeout. It is based on the successful and very effective Blackout flash suppressor line. The Blackout is probably the most effective flash suppressor on the market today. It will be interesting to see how much of that effectiveness the Brakeout retains. If it can suppress flash nearly as well as the Blackout and add some muzzle rise compensation it will be truly impressive.
Flash suppressing compensators are starting to fill the market. I own and use two PWS FSC556 flash suppressing compensators and they really do work. They reduce muzzle flip noticeably – which is saying something on the already mild muzzle flip of the 5.56. It also suppresses flash just as well as an A2 flash suppressor. The FSC556 and devices like it can give an already good shooter a needed advantage by decreasing the time needed to realign the sights between shots.
This type of performance does not come without costs. They increase (or at least redirect) the noise that comes from the muzzle while shooting. This extra noise may not be apparent to the shooter who is behind the rifle (as is the case with the FSC556) but it may be painfully obvious to those to the sides of the shooter. The extra (or redirected) noise will also become apparent when shooting indoors. Shooters who will be using these devices in team settings or on home defense guns should take note. The muzzle blast from these devices can also cause debris to be stirred up and rained down on the shooter when using non-standard shooting positions like roll over/urban prone. Any shooter who is considering one of these devices should educate themselves on the down sides before purchasing.
It should also be noted that these will not make marginal shooters into good shooters. If you do not apply the fundamentals of stance to control recoil, you will see little to no gains from these devices. While they do compensate for muzzle rise, they do not compensate for training, practice, or skill.
The sounds suppressor mount version of the AAC Brakeout is available for purchase now from AAC. I believe that eventually there will be a version without the suppressor mount.
