I got what I was looking for I just wanted to assure myself I ordered what I wanted .
eh? huh? what?
I dunno what he's referring too. Putting the dot on the tip of your front sight post will get you on paper, assuming your irons are sighted in correctly. But you should sight it seperately. I always find that you need to make a few adjustments. Tho both of my RDS didn't take more than a couple clicks of adjustment, I did have to make them.
Whether you run absolute or lower 1/3, the front sight will invariably be mostly out of the picture. The beauty of the RDS is that you don't have to have the same exactly check weld, like you do if you were using irons. With Irons you want your eye in the exact same place so that its easier for you to line up your sights. With a RDS you want a consistent check weld so that the dot in the same place every time you shoulder your weapon. You don't even look at the RDS. You focus on your target throught it, and let the system put a dot up for you. In the diagrams you posted, both sighting sytems will look about the same as the center diagram when you are using your red dot. The difference is that absolute will take up a little more of the window. I mean the difference we are talking about is like 3/8s of an inch. Its really not too much of a big deal. I have 2 Aimpoints both on KAC mounts. I chose the KACs because the heights are adjustable to 3 different levels, (it comes with 2 spacers) I've played around with the heights, and found lower 1/3 to be more comfortable for me on my carbine, and on my pistol I use no spacers because of the rise on my rail given by my VLTOR rail, (which makes it more like a lower 1/4 cowitness! :P)
