  • The Advanced Armament Corp BLACKOUT Muzzle brake is a multi-capable muzzle device.  This component is primarily designed as a muzzle brake, with dual, side facing ports to direct gases and mitigate recoil.  In addition to being a very capable muzzle brake, this muzzle device also serves as a mounting point for AAC sound suppressors with a 51-Tooth ratcheting interface mechanism.  This interface allows you to quickly attach and detach your sound suppressor from your host rifle.
  • The 5.56 BLACKOUT brake from AAC is made from 17-4 steel, which is aerospace grade and has been heat treated for increased strength and durability.  In addition to this, the steel has also been nitride to increase the surface hardness and increase the resistance to wear. 
  • This muzzle device is compatible with the following AAC Silencers…
    • 7.62-SDN6
    • ACR-SD
    • Mini 4
    • Mini 7
