I ordered two. 7.62 and 5.56.
I personally think you should do some more scientific style videos. I think they'd serve your sales well, and they'd probably be fun/interesting to do. Specifically, draw some lines on a large sheet of cardboard, and fire the rifles with the camera side-on the the muzzle/cardboard, so viewers can see the recoil and measure it against various other brakes (or brakeless) firearms. I love videos like that.
