The 1.5-8x IOR is a great choice. It's too bad the 35mm tube limits your mount options. I assume you'd use the included rings, but how will you mount it to your receiver?
I'm under the impression mounting it directly to the receiver rail will result in a scope position that's too far back.
Have you considered the
IOR 2.5-10x42mm? It's a bit cheaper, and the 30mm tube will allow the use of LaRue's excellent
LT 104 mount.
I used this mount with my 1.8-10x37mm USO, and the position is perfect.
EDIT: Nevermind, I see you're using LMT's MRP upper. That's perfect for the IOR 1.5-8x26mm as you can mount the scope exactly where you need it.
I'd also vote for the
IOR 2-12x32mm if you'd like to have adjustable parallax.
And if Burris ever decides to ship, their
3-12x50mm XTR might be worth a look also.
Finally, the
Nikon Tactical line deserves your consideration. Here's a recent thread on Snipershide.com
