What screw pitch do I need?

I have a Rem. 700 BDL from 1989. I am rescoping the rifle with a scope with a larger objective(50mm). The old scope was maybe 40mm obj. and it barely cleared the rear sight. I removed the rear sight but now have a couple of unsightly(no pun) holes in the top of the barrel. If I were to buy some headless screw plugs, what screw pitch size would I need. I think the diameter is 1/8" but what pitch? 8-40? Thanks for enlightening an old guy.

Thread pitch is 6-48 you can get them from Brownells or try a local gunshop to just buy a few. http://www.brownells.com/rifle-parts...prod10223.aspx

In a pinch, you can make your own with some old scope screws you have laying around in your box and a dremmel with a fiberglass cuttoff wheel. Screw it in until you find the right depth then mark that depth with a tiny sliver of masking tape. Unscrew the screw and grip the head with a pair of vise grips. Use the dremmel to cut off the tip of the screw at the mark. You now have an unheaded screw with one good end and one ragged end. Put that little screw in your vise grips with the ragged end out (don't grip too tight or you'll bugger the threads). Use the flat side of the wheel to polish the top flat. Now, very carefully, use the edge of the wheel to make a screwdriver slot. When that is done, get out your torch. heat it cherry red and douse it in a bit of motor oil. That will do a decent approximation of bluing. You now have a home-made plug.

Personally, I have never seen any problem with using regular plug screws. That is what came in those rifles and they don't look ugly or out of place to me.

6-48 will fit about 90% of the screw on sight and scope mount holes out there. A few extras are not a bad thing to have laying around. if you have a Marlin lever action or a Rem. 788 they take 8-40.
