Interesting ...
The version you posted is FRM-72-27 / Rev 17 / 07.08.10 and is 4 pages in length.
The latest version I have is FRM-72-26 / Rev 21 / 07.08.10 and is 7 pages in length.
Both contain some Gen4 parts but the short version skips a bunch of categories including but not limited to; extractors, firing pin parts, locking blocks and pins, magazine catch parts, and trigger parts.
Something is odd here. Not sure why these parts were omitted from the version you found online.
EDIT: I just e-mailed you my version in case you want to host/post it too.
