Repro Smith Carbine Cleanout Screw Thread/Pitch
(For the Googling WebCrawlers)
Hex Cap Metric M4-0.70
Make it short (3-4mm), or grind it so.
Personally, I found even slightly longer does fine as the chamber is bored in
such a way to stop it at proper depth, and the hex-socket/some anti-seize
grease make it a breeze to remove for cleaning
