Please forgive me for reviving an old thread, but with all you SW22 owners in here, I thought this might be the best place to ask a question.

I'm looking for the specs to the screw for the front sight? I thought it was a M4, but it's got finer threads and I don't have anything to compare it to. Local ACE was no help either.

I have the metal pic rail on it with a red dot and not using the front sight so I want to put a set screw in it to keep it crude free.
