The Winchester 2-Piece Scope Mount with Integral Rings are just like part of the receiver. These bases with integral rings and base virtually become part of your Model 70. The tight connection and one-piece design lock in your scope for the consistency and accuracy you demand. Integrated bases and rings are an excellent way to mount your scope closer to the bore centerline as well. The Model 70 integrated bases and rings are very secure, which means they will ensure your scope will stay zeroed in no matter the adverse conditions and wild weather.
