      Bubba did it !! He drilled wrong, the sight on my little mauser.

      I set up the barrelled action on a drill press, got the rear ghost ring sight in place with a parrell clamp, turned a drill bushing to keep pilot drill on center, used the drill press as a hand tapper.

      It was just great, nice & true & straight up-n-down, but the sight screw wont go in !! ??

      I run a burr out with the tap, an screw still wont go.

      Come to find out the screw is 6×48 and Bubba ran a 6×40 tap into the reciever. (only 1 hole so far)

      I looked everywhere for 2, 6×40 screws with no luck.

      Now what do I do?

      Got a large Ace hardware store close. In the nuts and bolts section there usually a decent selection of gun screws and will be labeled as such. Well made and blued and ready to go. When I was in the gunsmith business I often needed screws for a job only to find I didn’t have this or that. Ace hardware was the place.

      Saw a great selection at the one in Athens (Tx)  just this week when picking up bolts for a little project. Now not all Ace hardware stores stock em. Little ones don’t usually do but big stores will.

      No, I already exhausted all the hardware stores near me.

      Midway nor Brownells has any 6-40.

      4 screws are in an envelope and ready to go. Where are they going? PM me your address.

      (These will need to be cut to fit.)

      Hell, I keep all that truck in stock here. Hardly ever have call to use the 6-40s though. Good to have them handy just in case.

      I’d like to know how I got to here.

      I have drilled/tapped for scope several times., but not in 15 year or so.

      But, where did I get this 6-40 tap? What am I doing with it? how it get here??

      Late follow up here but 6×40 is a staple thread size in radio controlled airplanes.  Any hobby shop that caters to RC will have socket head capscrews.  Companies like RTL Fasteners and Microfasteners carry them in a variety of head styles.
