Hi all. I am trying to mount a scope as close to the bore as possible on a Winchester M70, 300 WSM. It is a 42 mm objective. I would like to mount it on a rail platform if possible. However, this puts the scope higher than I would like it. Does anyone make a picatinny rail shorter than .38" high? Most of the height of the Picatinny rail seems like wasted space. If there was a much lower profile rail, I could mount low Seekins rings (or something comparable) and get down just as low as I want. Thanks!
