BrakeOut2 appears to be shipping:

While I designed this and so am not unbiased, it was independently tested by Remington's R&D facility and scored 31% better recoil reduction than a Brakeout1, and 99.6% as much recoil reduction as an AAC dedicated two-chamber brake - so it really does obsolete normal muzzle brakes. Flash reduction looked almost as good as a Blackout. This does not need timing because it is symmetrical.
