Hi all, Just for academic discussion, what is the proper designation for the pre-M4 weapon we commonly call the "baby Armalite"? 1. M653 (as the Scout Rangers call them) 2. CAR-15 (as it is commonly known in the States; also in BlackHawk Down, the book) 3. M16A1 carbine (as called by Peter G. Kokalis, formerly of SOF) 4. All of the above?
