I recently aquired a nicely sporterized (the metal work, anyway) 1903 Springfield that is chambered in 300wm. The rifle is drilled and tapped for a two piece Weaver base and the bold handle has already been turned down. By the way, serial range puts in into the 1930's so no worry about an early brittle receiver. I have a Leatherwood ART M1200 Compuscope that I think would work great on it. Unfortunately, I need to come up with a Picatiny rail to mount the scope to. I can't seem to locate anything. Any ideas?
