1980's Armsport Hawken parts?

I have, and really enjoy, an Italian-manufactured Armsport Hawken I bought back in the late '80s, I believe. At some point over the years, I apparently buggered up the screw slot on the bolster/clean-out screw. I can still remove it, and filed the slot a bit, but would like to replace it.

Does anyone know of a source for this tiny screw? It's not a really big deal as I'm sure if I can't find one, I can drill and tap the hole for a known size replacement.

Undoubtedly a metric screw. If you have an Ace hardware nearby they carry metric setscrews in various sizes and lengths take the screw with you and they can I.D. the thread.

I might even have a set screw in the shop that will fit. I used to be really into R/C airplanes and have a bunch of small metric hardware. I'll see if I can match that size and thread pitch.
