Carnage_7, I sent you an email. Not sure if it was successful. Let me know how the installation turns out. Although I'll probably have ordered one.
Did you order the fiber optic sight? Front and rear, or other combination?
Did Danial give any other reason for going to a .305 height than the Pro has a 5 in barrel. By raising the sight height, the point of impact will be lowered. Anyway, that is my understanding. As always
