Glen, owner of Independence Training in Prescott Valley Arizona has included my muzzle flash results in his newest video. It is very well done and I suggest checking it out here. If you want world class firearms, trauma care, predator hunting, or outdoor survival skills training you can't beat this outfit. Visit his training site at http://www.independencetraining.com/ to learn more. I have had the opportunity to train with Glen and his crew on several occasions and cannot say enough positive things about them.
My blog entry on muzzle flash testing can be found here.
