What government really would want a bunch of worn out M16’s from the 60’s? M16’s can be a very effective weapon, providing they’re well maintained and not worn out, but I’d bet any M16’s in VN’s armories are neither. I handled plenty of old jammomatic M16A1’s back in the 80’s and I hated them, but when they gave us new M16A2’s I had to change my opinion of them. The new rifles were both reliable and accurate.
A properly trained soldier always takes care of his 'stuff', who knows maybe our Army there will perform a miracle?
