I have a set of Redfield spilt rings, 1 inch, model #522605. I am not sure what the screw size is and where to pick up some. I have did some research, but not sure, .Are they a 8-40??
Thanks
 
Do you have a big Ace Hardware in your area?

My Ace has about four aisles of fastener hardware.

I was surprised to see that they actually carry blued "gun screws" in those oddball gunsmith threadings.
 
Hope they have something. I was shocked when I saw the two trays sorted into a shit ton of blued screws of various lengths and thread pitch.
 
Redfield rings like these?

I do not have any extra screws, but I do have several sets of rings which I am going to sell in a few weeks with some 1970's Redfield scopes & bases.
Some of the rings are: 522000 Low; 522600 Low; and 522605 Medium. Sorry that I cannot sell a set right now, but someone may want a matched set of scopes, rings and bases. I purchased this stuff from Redfield in Denver around 1970.
