I just bought a 20 year old DSP Sporter, which I am just crazy about! This one I plan to shoot with open irons only.
Anyway, when I got it, there was no rail mounted to the top of the receiver, but there are some marks indicating that one had been there. The four holes are open (no screws). To finish off the top of the receiver, I'd really love to find some flat top screws to plug those four holes with and I believe they are 6-48 screws... and must be extremely short.
Does anyone happen to have any of these that they're not using? I'm having a difficult time finding this size screw. They are extremely uncommon outside of the gun scope world.
Thank you.
Oh yeah, I hear Pirates like photos

... here's the gun:
