Vortex 2.5-10x FFP riflescope. Msrp $899.99
Vortex Optics - Viper PST 2.5-10x32 FFP EBR-1 MOA
Or
Vortex 2.5-10x Second Focal plane riflescope. Msrp $699.99
Vortex Optics - Viper PST 2.5-10x44 EBR-1 MOA
Both can be had for about $100 less if you shop around, and most places will ship for free. I would love one of these in a ADM mount. Personally, I would go with the Second Focal Plane model, and get a good quality one piece QD mount with the money I would save. The bell is just a little bigger as well at 44mm compared to 32mm on the FFP model.
On a side note, I love ACOGs. I suggest you keep the 17s as badass as possible. Get a bigger ACOG.

Go for a British "sharpshooter" style with one of these.
TA648-308 ACOG - Trijicon, Inc. - Msrp $2680.00
militarywarfighter.com has a great selection of ACOGs at decent prices. I have no affiliation with them other than purchasing a rifle scope after very long discussions with the owner. He took the time to help me in every way I needed and I even learned a few things. Hope you have fun in your choice for a new optic!
