The LaRue HK416 mount for the Aimpoint micro sights says it will give lower 1/3 cowitness with the HK sights, IIRC. If I use it with standard back up sights it'll be a center co-witness, or close to thereabouts, correct?
O.K., I would say that the T-1 on the Larue 416 mount is pretty damn close to a perfect absolute co-witness with a standard height BUIS. Actually this test has made me think about picking up another Larue 416 setup for the T-1 on my LWRC.
Troy's are what I have so thanks for the help! When my SBR papers come in I was thinking of going with a smaller optic. The lower 1/3 cowitness is fine but I don't like the HK sights myself and I don't want that little optic sticking up so high on that mount. As long as I can use the sights through the optic when/if I should need to then I'm golden.
