Ok been reading through the forums and found some info but nothing in concrete, which ADM QD mount for 1/3 co-witness, the SOCOM? It says in one of the post that the SPARC sits a little higher than a T-1 so this would have an effect on the sight picture. Does anyone have the SPARC on a regular flat top M4 (Colt 6920) with standard FSB and a Troy flip up rear sight. I am looking for the best set-up for this optic to start trying it out.

Thanks!

First Thing you need to do is tell us what front sight base you have. You state a colt flat top and say a standard FSB. That does not make sense
Second thing is a lower 1/3rd Co witness would lead to a mount being a little Higher than absolute cowitness. Please restate your question.

You'll probably want the absolute cowitness mount instead of the socom(lower 1/3) mount as the position of the LED will intefere with being able to see you sights...not a huge deal if you have flip ups front and rear as you probably wont use them and if you are going to take a sec to flip them up you can just as easily QD the ADM mount/optic

Ok sorry, I have a Colt 6920 with the carry handle removed (flat top) a Troy industries flip up rear sight and the factory standard fixed Colt front sight (triangle), yes I was told yesterday by rainier arms that I do want the absolute co-witness ADM mount for the SPARC. Does that sound correct? Thanks and I hope I explained things a little better.

I'd love to know as well - I've got an Adams Arms piston upper with same rail height for front gas block and rear sight.  Want to make sure it will clear the LED in the view and not block the front sight.

I ordered the Larue Tactical LT660HK, from a couple different post I read on here, members say it will work almost perfect. I will report once it arrives.

Thanks

Larue Tactical LT660HK works absolutely perfect! I am taking unit to work with me tomorrow, training Sergeant for DOD police agency, work is a full service range for tri-county law enforcement, I am going to let as many people (mostly LEO) I can shoot it and put the SPARC through its paces for a couple days.

Could someone remind me of how the cowitness looks through a SPARC with the LT-660HK? And has anyone tried the new LaRue mount designed for absolute cowitness with the Aimpoint? I know the tall 660 is too high. I am trying for somewhere between an absolute and lower 1/3 cowitness with a SPARC. I am planning to use it with fixed BUIS. Thanks.

With the 660HK from Larue, it's an exact cowittness.   The dot sits at the tip of the front iron sight.

Update:
