We are offering these factory Colt M-16A1 parts sets that have been found overseas still sitting in the crates unissued. These rifles were brought back into the United States and had to have the lower receiver and barrel destroyed in order to be released for sale. We have a VERY limited amount of these sets in stock. ALL NFA/BATF RULES APPLY. These parts are not for sale in cities/states that do not allow the full-auto parts.
