Where could I find Weaver style rings for a 3/4" diameter scope( Weaver 330 or Lyman Alaskan). Or where could I find 3/4" inserts for 1" scope rings? I am looking to convert a 1903A3 to an A4 without altering original rifle. Plan on using S&K non-gunsmithing weaver style mount(anyone had expirience with this mount?). I will also get a low scope bolt body and safety and a replacement "C" pattern stock. Oh and does anyone know where I could find a used Weaver 330 or Lyman Alaskan for a good price besides one of the various auctions? I could also go with a look alike scope like a Weaver 440 Or somethimg else if it was cheaper rather than an original. Thanks for your help!
