I have a M33 rolling block and the installed sights are pretty poor. so I was able to buy from a member here a Lyman peep that matches the finish and is the correct height. Now to mount it.
The tang screw is long enough but the screw head profile is all wrong. My question is does anyone have an idea what the thread size and pitch is so i can try and make a more appropriate screw.
I will have to D&T a screw for the forward mounting hole but again i will have to find a good looking old screw or make one for there as well.
