I should have specified, the reason I'm putting data together is because I'm planning on going over his head and sideways to the other firearms guy (who won't do it on his own, but can be swayed). The big boss man can also be swayed, but only with good cause (some hard data and a reason for disregarding the word of the firearms guy). I imagine the point will be conceded when I have a bunch of info and whatnot to present. Step 2 is getting him to the range and saying "here's a T-1, here's your iron sights. Try them both out and pick which is easier"
Thanks for the input!
