@BlueMouse "Not like they have stolen all ACOG scopes in existance; it's a fairly common/popular scope for Western armed forces, so it's constantly being produced on the Western side."
Well it ain't being produced for the west/security in INS:S bahaha. Like I've said before, if the ACOG was to stay on the INS, I'd rather see it be an older TA01 model with it being all dusty and roughed up just like how the M16A2 is all dirty. This would still fit your story of INS claiming a western cache of equipment. Then give the newer ACOG version to the SEC side.
Surprisingly, the ACOG is available for SEC weapons in checkpoint (but pretty much everything is available), so its not like they have to do any work to make it available for the SEC in push/firefight/skirmish because it's already possible in the game just in the wrong area.
