Tom, I think BSA makes a Tactical Weapon series 4x30 with a Mil-Dot reticle. Not sure about the quality.
So where along the line I heard that a lot of scope manufacturers mil-dot scopes are not a true mil-dot. Might be something to check out before you purchase.
I vote for the M1A, but I'm old school and like blued steel and wood, plus I think that the M1A is the epitome of what a battle rifle should be.
