I have no dog in this fight, but the gentleman in the video is a reputable instructor and has the experience to back it up. What's wrong with him marketing his services?
This not directed personally to you, but it's annoying to see this kind of attitude as it normally drives quality posters away or at a minimum serves no purpose.
Indeed. Furthermore, the "mag flippy thing" is very much a legitimate technique to ensure that the spent magazine actually drops from the rifle, thus minimizing the number of times the user has to use use the support hand to strip the magazine. Probably not as useful for an AK, obviously, but it's also good for handguns as well. You can't reload until the empty mag is gone!
I figured my sarcasm would have been received regardless of text color. I guess I will edit my post.
