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...
