Hello, everyone. I just recently joined this forum to try and get some help with my AR-15 I bought. I've got it mostly how I want it except I need a little help with the optics. I bought a EOTech 512 HWS and am thinking about purchasing a 3x magnifier from EOTech. The part that I need help with is zeroing the magnifier and sight together. Does anybody have a video or how to on how to zero it for about 200 yards. Thanks for all the help.
