Dave I'm assuming that's you.
I was also fortunate enough to be able to test the Antidote hands on this past weekend with Rifle Dynamics. Yes, it is a large price tag but I feel it is completely warranted. The construction and performance of the device is well worth the cost in my opinion, I even ordered one for myself.
From the different brakes I've had the ability to test, this has has been the highest performance one yet. It performs the same as a Surefire 7.62 muzzle brake, yet there is much less concussion to the sides and to the shooter. I feel it out performs the BCAK.
