If I install a magpul mbus rear sight with a stock iron sight will that work? Will the magpul sight be too low for the iron sight? What kind of optic can I use with this set up?
I agree. That's the way I prezero a RDS before going to the range. I know my irons are right so just lollipop the red dot on the front sight and go. As long as you have a good solid mount then the reverse should work as well.... I just received my MBUS rear sight and installed it. my optic was already installed and zeroed.
when the rear sight is down, its flat and out of the way of the optic. flip it up, and take a sight picture through the peep hole, its nearly dead on to where my red dot is... I haven't fired it yet, but I'm going to assume that when I look through the peep, and take a normal sight picture with the front iron sight, and it all lines up with where my red dot is, that my iron sights are dang near zero.
