Absolute co-witness advice needed

Tactical Gear Optics & Mounts
1

My intentions are to put a Vortex Sparc (same basic size and dimensions as the Aimpoint H1 & T1) onto a Laure QD mount for my new BCM upper. It currently has folding Troy Night Sights front and rear and I want an absolute co-witness.

The research I’ve done so far has indicated that there are 3 possible Larue mounts to consider: the LT660HK, the LT661 and the LT751.

I like to design of the LT751, but I am willing to use any of the Larue options that get the final results I’m looking for.

What is your advice considering my preferences?

Thanks.

I use the LT751 on my SBR and the co-witness is perfect. Return to zero is also absolute.

I run a T1 on the mount.

I think the only way you would have an issue is if the optic you are going to use is not EXACTLY like the T/H1, otherwise you should be fine.

I would also recommend giving Larue a call, they may have some experience with the combo you are considering.
