i clear storage units for a living. I found two rubber duck m16a1's in a unit and I am trying to establish what I should ask for them to sell. I am not a collector and these are out of my field of "expertise" really. I have contacted a few local military places to ask them but as soon as they see them they ask me how much I want and won't give me a value. one is 100% rubber. One has a steel barrel.
