Leapers makes a plastic (IIRC) Commercial... but I'm not sure how far I'd trust it even though I have one of their optic risers on my AR. And Tony at Tony's Custom tells me he does sell the stock bare, though I forgot to ask if it was Commercial or Milspec.

Don't know if they're still cranking out fresh, but I know Diemaco was cranking out a lot of 'em long after Colt went to the modern M4 because for some reason the Canadian military preferred the old style. Maybe Troy has a few extras from their XM177/GAU-5 replica runs...

Not an expert, just been doing some looking into this myself. Hope some of this helps.

EDIT: FOUND IT, and it's Mil-Spec! http://www.combatprep.com/XM177-STYL...CK-p/j1122.htm They've got a waiting list already started for the next batch.
These folks may help:
