If you strip a 10/22 scope base hole, Brownells sells a kit............about 40 bucks, for the tap and screws.
Do not need to mod your 6-48 screw scope base.
Can get w fillister or Weaver type screws.
Screws are long and need to be ground to length.
I bought an old 10/22 ('67) with a boogered up hole and got the kit.
Thanks hookeye. I 'think' I am good now and trying not to fix something that is working for me- know what I mean? Reminds me.....order replacement stock for ADL !!!! grrrrrrrr
