I have a FN Mauser action from the late 40's early 50's. Looking for Picatinny style ring bases. We could live with a rail and would prefer two piece. We can cut down a rail if we had to. The rear of the receiver is lower than the front by .208". We can shim it with some lead sheeting, and again would prefer not to if possible. The front hole spacing is .861" c/c and the rear is .516" c/c. Open to suggestions or if anyone knows where/what will fit. We can drill and counter sink new base holes if there is enough room between the stock base holes. Any assistance is appreciated.
