Does Anyone know if the Eotech 517 will co witness with the stock troy sights that come on the Ruger SR 5.56 or should i buy the 512??.......also if anyone else has any suggestions on any other optics that would work well with this weapon platform... thanks

Or possibly even a Trijicon Reflex sight?

eotech 517 co witnesses in the lower 1/3 of the window on my Ar, (stag upper), works very well. I would imagine the sr556 would be the same.
Why Co-Witness ? It makes the field of view too cluttered. Lower 1/3 for the irons is the way to go.

I still remember in 1989 when Bill Ruger wrote Congress to Ban Hi Cap mags.....

I probably mis-typed, 517 is lower 1/3 but not co witness? Got my terminology bass-ackwards.

You are correct. They are mutually exclusive.

Now all you need is some quality Carbine training to go with your new blaster. ;)
Yea There should be no problem.  Co witnessing them irons.  
my concern is will the eotch be to high to see through with the stock troy folding sights that come with a weapon
The 517 is lower 1/3 co-witness with standard height Troy sights. Does the Ruger use different height flip sights? I wouldn't think so but I'm not positive. Not sure why it would.
You mentioned other reccomendations, you might be interested in the Aimpoint Comp ML 3.  (I like the 2 moa dot).   They are very good sights.  I have Eo Techs, Aimpoints, Trijicons and Leupolds, and for the non magnifieres, I personally like the aimpoints.  
I have a Troy DOA BUIS co-witnessing with my EoTech 552 and it works well. I was mitchell field today with it and im loving it more and more everytime i shoot with it.
