Aimpoint Micro H-1 mounting questions... need help from experts

[Balrog]

I have been looking at red dot scopes to go on the rail of a Colt 6920. I think (but not totally decided yet) that I am going to go with the Aimpoint Micro H-1, I am looking at mounting options, and LaRue mounts have been recommended. Looking at their website they say the tall mount will provide a 1/3 lower cowitness. What does that mean? I have an Aimpoint CompC3 on another AR, and I have it set up so it cowitnesses with the front sight.

Does the tall LaRue mount get the sight up too high for a good cheekweld?

Coronach?

The difference between absolute cowitness and lower 1/3 cowitness (front sight floats 1/3rd of the tube diameter below the dot) is maybe 1/4".

I prefer having my dot clear of the front sight. If it fails I can drop my head by a fraction and pick up the front sight. BSW

Yeah, the height will be the right height for an AR if you use the LaRue mount. If the sight set up for lower 1/3rd cowitness, it just means that the dot will appear to float above the post if you look through the rear peep sight, and if you lift your head ever so slightly (still keeping proper cheekweld) and look over the rear sight (or flip it down), the front sight will seem to be in the lower 1/3rd of the optic, and the dot will be centered. Some people prefer absolute cowitness (dot would be on the post if you looked through the rear sight), but I, personally, think lower 1/3rd is better, since it gets the irons down out of the way. They're still there for emergency use, and once you deal with immediate problems, you can throw the QD lever and jettison the dead optic. Either of the cowitness setups will work, though.

You really can't go wrong with the LaRue mount.

Thanks for the info. I believe that is the set up I will go with... I will post an update on how it works for me.
