Perhaps a dumb question, but I'm having some trouble coming up with a good method to make certain my new (to me) aimpoint comp M is level. I've used those scope-level doohickies for traditional optics with crosshairs, but there's obviously nothing in the aimpoint recticle to use to index. Not really a nice flat surface to place a level, either, or I could just make certain the scope was level in relation to the receiver that way... Perhaps I'm missing something that is explained in the manual, but I don't got one. I guess if you're just gonna set it and forget it, it isn't that important it be perfect, but if I need to make adjustments, I'd like to know that each elevation click is .5MOA in elevation, not just about .5MOA elevation and a tad of windage... Oh, using the QRP mount, BTW, if that makes a difference... Rocko |

The only way the Aimpoint would not be level is if the mount it is in wasn't level. But odds are that the QRP mount is level and you should not worry about it. Just make sure that the Aimpoint sits in the ARP tight and that you tighten the screws completely so the Aimpoint does not move in the mount. |
Don't worry about using a level, mounting via a level will not work, because of many factors. All optics have windage and elevation just like the weapons iron sights do. Put it on the weapon and zero the scope to a target, not the irons. If the weapon has irons, and are on target, you should have no problems unless as mentioned you have a bad mount, which is very unlikely.  Jack |

Thanks Troy, the cap probably isn't the best surface, but looks like that's about the best option.... Looks like I wasn't perhaps being clear in my original post, though - didn't mean front to back level, as the first two replies seem to point to, but rather in the direction of rotation within the ring... Worst case scenario, imagining that the scope is twisted such that the elevation dial is pointed 45deg off perpendicular. If I then dialed in 4MOA of elevation, it wouldn't be 4MOA change in elevation, but the square root of 8 in both elevation of windage (darn you, making me remember trig!). Of course, I'm able to get it a bit better than 45deg off by eye  but I think you can get the point...Rocko |
| I see no need for a level if you properly installed your Aimpoint in its mount. I used a QRP mount for years without ever needing a level. Just take the time to use a crossing pattern when tightening the four mounting screws and try not to make one side tighter than the other. I also check to make sure the gap is the same on both sides of the mount. |

Rocko, even if no one else understands your position, I do. What he is saying is that he wants the Aimpoint to sit perfectly rotated in the mount, with the elevation knob cap at the 12 o'clock position and the windage cap at 3 o'clock. If the optic is rotated even a slight degree to one side or the other, his vertical and horizontal adjustment axises will be off. An adjustment to one of the knobs would cause the POI to move diagonally instead of vertically or horizontally. Granted, you could still get it to zero, but it would be a PITA if you ever needed to adjust it frequently for different ammo or some other reason. A good example would be having a crosshair-style scope with the crosshairs in an "X" instead of a "+". |
What difference would that make with an Aimpoint? |
I eyeballed my M2's in their mounts and my POI's move up/down & left/right with no problems. I believe that once you get out and actually shoot with your Aimpoint you'll understand how you over analyzed a very simple process. Chris |
