I just received an Aimpoint Comp M2 2x, which I'm planning to mount on a DSA carbine when the mount arrives. Having never tried a 2x Aimpoint, I quickly installed the battery and cranked up the knob. Very nice.
Sitting on my couch, I checked it out and discovered a problem. When I moved my head, the dot moved too. Hmmmm, I thought --- this doesn't happen with my EOTech or any other Aimpoint with which I have jacked, so there's something wrong: parallax. I put the M2 2x on my desk and taped a ruler to the wall about 10 feet away. Shifting my head so that the dot moved from the far left to far right border of the reticle, parallax put the shot in a 2" circle at 10 feet.
But I was still thinking that good quality red dots aren't supposed to have parallax, so I checked Aimpoint's website, various other red dot ads, and HR's and TFL's archives, and every article said that good red dots don't have parallax, so is it just my luck (bad) kicking in?
Or is there something to magnification that creates parallax? I checked the Leupold Mark IV red dot specs --- the specs say that the Mark IV's parallax is factory adjusted for 150 feet and nonadjustable by the user. Does this mean that at 150 feet, the Mark IV has no parallax? Does this further mean that with my Aimpoint, at farther distances, the parallax will decrease until I get to Aimpoint's designated parallax-free distance?
I'm hoping that someone can enlighten me. A 2" circle at 10 feet is plenty good --- I just have to remember that for surgical placement at close distances, the dot goes in the center of the reticle, about 3" above the intended POI, with a noncanted weapon, except on Thursdays under the full moon.
But I'd still like to confirm that magnified red dots do indeed have parallax. Thanks for your thoughts!
