I have finished watching a couple training DVDs and noticed both instructors used the same brand AR. This piqued my curiosity so I did a quick search. It seems like a good portion of the high end instructors use 1 of 3 or 4 AR brands. Let's have a little contest. See how many top instructors you can find and note what brand of AR they use. Report back here w/ your findings. The most thorough list wins.
