I have a AR15 topped with a Larue mount putting the scope 1.5 inches above bore. I used the aimpoint in the army with 25 meter battle zero with great results but now am going to have a Mil/Mil scope and be working the turrets. Where are you guys setting your zero? My main goal is to make hits at approx 200 to 300 yards. I am thinking zero at 100 and dial up from there. Is there a better way?

if 300 is your max distance and you have a range you can zero and confirm a 300 zero on, then do a 300 zero. Some call this the marine corp 36/300 zero and it does have some merit as it gives you a combat effective diameter of something like 2.5 " from 25m out to 300m poa/poi.
No the scope mount is 1.5" high. You have about another 1"+ to get down to the bore. You will need to measure it.
That said, scope height above bore doesn't matter much to the question. It will only matter when you run the numbers on a ballistics program for data. You need to figure out what type of shooting you will be doing, ranges and scope used. I zero my 3 gun 1-6x scope at 200 yards so it's dead on at 50/200 and about 2" high at 100 and then use the BDC lines for 300, 400, 500 and 600. Never touch the dials.
What scope you using? If you plan to dial data using a higher power scope for precision work then just use a 100 yard zero and dial.
I will be using a Bushnell elite tactical 10x42. I missed a deer this weekend with my 30-06 due to it being in an unexpected place, and me not knowing the dope on the round. So I will go to the range tomorrow and get my AR dialed in. If I had been using the weapon I used on the qual range I would have nailed this deer. I am pissed at myself that I missed a deer with a 9 power scope that I could have hit with my aimpoint.
How far away was the deer? Out to 300y it's not that difficult to "swag" a vital hit on deer sized game, even given just the "dope" on the back of the box of factory ammo. Either way, set your zero based on your shooing needs. If you are shooting 300y, set the zero for that. If you are shooting 0-x, set the zero for the most common range then empericly determine come ups out to "x." What I use for a zero may not work best for you...
