I'll have to look into building myself one. How did you control the elements and stand them off the pvc?

For my 1905 Ross project, the screw is the one on the front of the front sight base that seems to clamp the sight in. Original had been mangled before I got it. Someone put an odd sight in it and they piled on solder. It's a 5-40 screw a little over 5/8" long. I've got some 5-40 allen screws, while not correct or as nice looking, they will be difficult for someone to damage down the road. If it isn't discreet enough, I'll make some closer to original. I just need to turn the heads down to sit in the counterbore and cut them to length.
