Is the MCTAGS OGPK Turret different?

[alwayskaos]

Ok….so Ive been researching all the info on the OGPK turret and came across a manual that shows exploded diagrams with part numbers. The OGPK has more of a flat panel in the back, and from the photos I’ve seen of the MCTAGS version, it has angled sides that connect to the back panel. I’m so confused
I’ve already started collecting the brackets, parts, and even purchased a Neptune kit for the back panel. I can manufacture the plate sides and gunners shield. I just can’t seem to find the part numbers for the MCTAGS version. Can anyone provide me a little guidance? Are there pros and cons for each one? Is there a TM that shows the MCTAGS version? I’ve been searching and can’t seem to find it. Thanks everyone!! I have an M1151 Rev BTW

Army uses OGPK
USMC uses MCTAGS

ARMY and USMC turret component parts are also different, such as bearings and slewing rings, I stock pretty much all versions of turrets And GPK’s
