I have a Savage model 4 and I'd like to add a Weaver B4 3/4 scope to it. I've bought every recomended weaver mount but haven't had any luck. the holes on the rifle are threaded 10-32 and are 1.625" apart. The N2 and N3 mounts don't line up and also crash the bolt into the scope. I bought Weaver 12 & 13 single mounts. Does anyone have a reccomendation for 3/4" rings that adapt to the 12 &13 mounts? Any suggestios are welcome....
