I picked up a nice stevens 53-B, but it had no sights. I found a rear peep that will work, but I don't have the mounting screw. it is a single mounting screw, I think it might be a thumbscrew. I tried an 8-32 screw and it is very close, but not quite right. the thread pitch must be close. does anybody have one that they can measure the threads on for me? IIRC a springfield 66 is similar, as is a stevens model 3.

thanks again.

ETA: looks like 8-36, will find out yet....
