Well, that is a worthless video! How much muzzle flip occurs due to that configuration? We'll never know based on that stupid video!
Are you still getting your Shot Show tickets via MGO/MGO's mailing address? I signed up via MGO as MGO's website/forum Administrator using the MGO address one time and got my tickets for Jan. 2011…and have never received anything since (other than LOTS of email spam every year since)!
Funny thing was, my (then) employer actually paid part of my expenses since we were a firearms industry manufacturer, but instead of going that route, I signed-up as a firearms industry website/blog administrator.
