The V8.0 USMC OOB has:
##############################
Unit#314 MH-47E Chinook 01/1995-01/2010 - 2xM134 Gat, Vis=40 FC=5 RF=5 Stab=4
Unit#316 MH-47G Chinook 01/2008-12/2020 - 2xM134 Gat 2xM240, Vis=60 FC=6 RF=6 Stab=6

So just need to change Unit#316 to 01/2007-12/2020 and FC=8
##############################
Unit#649 MV-22B Osprey 03/2006-12/2020 - 1xM2 HMG, Vis=15
Unit#650 MV-22B+ Osprey 01/2009-12/2020 - 1xM134 Gat 1xM2 HMG, Vis=40

Didn't include the MMG version because it's only around for a couple years and my "rule of thumb" is - If it only exists for less then 3 years don't include it else the OOB will swell like a balloon.

The best info I can find indicates they only mount the M134 if they know they're going into a Hot LZ (since it reduces cargo capacity and blocks the Hell Hole (which is used to rig cargo slings)

Cheap?
I may be a Harlot but never a cheap one!
