Huang,
This is very exciting heheh. As long as the mount locks on the side position, do what you gotta do! Please, build it to line up with an Aimpoint on a cantilever mount cause it looks like that's the same height as an Eotech anyhow. Then we can use the magnifier/mount on iether sight w/o a riser etc. Nice thing about the Larue is it looks like there is a lot of room for a buis there.
Will you sell the mount seperately? Cause I would rather buy it, and a Star Eotech replica magnifier to match my Eotech 551. I'm not sure I want aimpoint mag w/Eotech sight...

Aimpoint mag

Eotech mag (I like the covers too)
