Better try an screw in your bases to see what you are getting yourself into there. How are you going to cut the flat bottomed counter bore in the base for the larger screw head?

Yes, plus stronger. Thanks everyone for your advice it is much appreciated. Originally Posted by gzig5 Better try an screw in your bases to see what you are getting yourself into there. I have base screws and the head fits into the countersunk area of the base perfectly.

I'll just use the clearance bit to enlarge the screw hole and I should be good to go.

You're right about that. I do have a friend that can help, unfortunately he's moved his business miles from our current residence. I drilled and tapped the stripped hole and I was successful. When I attempted to screw the base down the other hole,that I had left alone,stripped out.

So I drilled and tapped the second hole and I'm happy to report that was successful as well. I now have the scope mounted and ready to be sighted. This is a Winchester 94AE without the dreaded safety. I've used it for six years with a Williams receiver sight and I've done well.

Then I noticed this year that I could no longer see the front sight as clearly as in the past years. So it was at this point that I decided that I needed a scope.

When I attempted to install the front base I realized the screw was stripped and my odyssey began. It's all resolved now and thanks again. I also have a set of the the piloted counter bores to make the recess for the screw head conversions but since I do the drilling with the mill so i just use the end mill NRA Benefactor Member Those who live by the sword get shot by those who don't.
