For you AR guys, If you notice the AR15/M4 that dad has in his hand (picture of him about to board chopper) That has the Adjustable stock and short barrel, looks to be a 14.5 inch or shorter.
I didn't know they had that style of AR back then.
I'll be posting more pics soon, if no one minds? (got a new printer, scanner just want to plat with it
)
