Absolutely I have that listed, regarding what instrumentation and standards he implies to make it fair for all suppressors on any given day. I do know that a few suppressor manufacturers take pretty big issue with him because of his unbiased testing and stance on testing and evaluation.
If anyone else has detailed questions on this subject and questions for him, by all means let me know.
Like, love, or hate TBAC, I appreciate and respect the testing Ray and the folks from TBAC do. Ray will test anything a manufacture is willing to send them and he puts it all right there on youtube to see. If something meters better than their stuff Ray has no problem saying so and will give kudos to them right in the video for all to hear and see. I'm unaware of anyone else that videos their actual testing, describes the equipment used, and puts it all on youtube like Ray does.
Maybe you could get them on together, that'd be interesting.
