I have a Colt M16 for sale. It's on a form 4 at my dealer in Indiana.
More Pics and more details available upon request. It's at my dealer but can get more pics from him as needed, email or IM for more questions. I've sold MG and suppressors on here before and have references.
Comes with a 10.3" upper - I recently changed the stock to an original colt m4 stock
Here is a pic with a different upper on it, all uppers I tried fit and function perfect.
