I recently picked up a SPARC for my CMMG 6.8 carbine and so far I am really liking this little optic.  I would like to change the mount out to an American Defense QD but I'm not sure which one I need.  ADM shows these four on their website;
1. Aimpoint T1 micro mount (seems to be a multi piece unit with spacers)
2. Aimpoint T1 micro mount 1 piece co-witness
3. Aimpoint T1 micro mount 1 piece SOCOM height
4. Aimpoint T1 micro mount CAS-V

I would like to know which of these mounts will give me an absolute co-witness and which will give a lower 1/3 co-witness with the SPARC.  This is going on a standard AR flat top upper with a standard, fixed FSB and folding rear Troy BUIS.  TIA...

If I recall correctly none of them line up perfectly ,but ADM (i believe) is in the process of doing a Sparc specific mount. Your best would be to give them a call.  Something else that might help you - the sparc will sit just a tad higher than the micro's no matter what mount they are in.

Thanks for the info Scott.  Based on that, looks like I might be best off going with a Larue medium height mount unless ADM has something new available.
