M2/M2 parts source

[BillinBama]

This may have been addressed in an old post, my search didn't turn it up though.  I lost the trigger housing pin for one of my carbines and don't have a spare.  It's in my basement somewhere, but so are a dozen AR springs that have launched themselves over the years, never turn up.  Anyway, in searching for a good source, I stumbled on a post on some forum recommending Sherluk, and even though it was a couple of years old they still list good prices on some otherwise hard-to-find parts.  I found lots of sources for the housing pin, but I also lost the plunger for the disconnector spring on my M2, and Sherluk is the only place I could find one.  So I thought I'd pass it along in case somebody else has a black hole in their shop that swallows small parts.
