The following weapons can be seen in Coming Home: (1978)
M16
SKS Rifle
Chinese Type 56 Carbine aka the Chinese SKS rifle - 7.62x39mm. The Chinese SKS has a stamped receiver and a spike bayonet (aka a "pig sticker") much like one of their
AK-47 copies - the
Type 56 assault rifle. This version, like many imported SKS rifles, have the infamous 'orange cratewood' stocks, probably the lowest quality wood in any mass produced rifle, save for the last ditch
Arisaka Type 99 rifles at the end of WW2. Many SKS rifles during the Vietnam War were issued with reddish plastic stocks, because of the incidents of 'wood rot' in the humid SE Asian jungles.
