I know nothing of black river tactical, do as you like of course but the brake I made was made to function better than anything out there with none of the drawbacks, it is made caliber specific and TPI specific, it fits like nothing else as well, no slop in those threads, no crush washer to keep it on.
It fits so well you could use it to correct a buggered thread.
