Here is a quick look at a couple of M16A1 shipping boxes that I received today.
One is dated April 1976 (contract date 1971)and the other box just has a contract date of 1971. There is some packing material included with the boxes that I will show at a later date.
Dimensions are 30-1/4 inches x 11-1/2 inches x 3-1/2 inches.
I truly find packaging and accessories as fascinating as the weapons themselves. That includes current products as well.
