Not sure if everyone else knows this already and I’m the last one but when I mounted these two scopes, after I used the two magnet method, I verified the scopes were in fact 100% vertical (as opposed to canted) using the flashlight method. If you don’t know what that is, you put your rifle pointed away from a wall. The rifle should be perpendicular to the wall/door. Make sure the rifle itself is level (don’t use the scope to sit a level on). Take a plumb line and hang it on the wall. I just used some 550 cord and a pair of rings. The effect is that the cord will be completely vertical. Next take a flashlight and shine it from the front of the scope through to the back and then onto the wall. The reticle will display on the wall. Move the plumb line over until it hangs so that the top of the vertical reticle shadow is touching the line. Now look at the bottom part of the reticle. If the scope is mounted properly, the plum b line will be covering the vertical crosshair. This makes your sighting in much easier. And of course your hits, especially at longer distances.
