Okay, you got my interest.
What are the specs for a #2 contour? I can't seem to find a contour chart on the web.
OR, as a minimum do you know the OD at the muzzle for the #2?
According to the MRC website the weight of their regular Extreme X2 in .243 is 6 lbs. 14 oz. Sounds like this one is the basic X2 model with the only difference being twist rate so I imagine that's the nominal weight. Add Talleys and a lighter scope and you're looking at 7 lbs, 9 to 12 oz unloaded.
