^ yes m16a2 is no longer used by any American front line military units, its Ether the M4 for army or M16a4 for marines both of which use optics(ACOG, M86 EOTech LMGs will most likely have an ELCan scope on them)

He is right this gun is no longer used by the Chinese they use the QBZ-95(Most of the time the average rifleman in the Chinese army has a scope on his rifle Same with every other conventional army) as their rifle and the QBB-95 as there LMG and the US no longer uses the M16A2 like you have there, the US Army strictly uses the M4 and the marines use M16a4's most of the time both guns have ACOG's on them and army uses M86 aim points.
