Thats gonna depend on the rings you choose.

For the most part I am able to use PRW or Maxima rings in low, weaver 4X4's in medium on a factory base. With Leupold, Burris, Nikon and old Redfield scopes.
Sometimes its quite close, but clears. Once I have ground a bit on the hammer to get better clearance. But usually not necessary.
