[ARCHIVED THREAD] - Technical Data Package (Drawing 12972700)

Posted: 5/10/2011 3:16:18 PM EDT

Ok, I've searched and searched (and hopefully I am posting this in the right forum), but does anyone have a copy of Drawing(s) 12972700? Spec MIL-C-71186 (AR) details this drawing as the place to where specified material can be found. I am specifically looking for the material used in the M4 barrel extension, though I believe it is AISI 8620. Any help would be appreciated. Thanks.
