I have a Buehler Micro Dial scope base with the letter code A U. Could someone tell me what gun it will fit, or where to look for a chart of the codes. I looked on google and found tons of stuff about Buehler mounts but nothing on what the letter codes stand for.
Thanks

The 1971 Stoeger catalog shows Buehler Micro Mount with code AU was for a Springfield 03A3. Hope this helps.
