I have been looking for a Colt pre-ban carbine for a while and recently ran across one offered for sale that the owner describes as a pre-ban "AR-15 Tactical carbine". I have only spoke with the owner (a local LEO) by phone and he described the rifle as follows: 16" heavy barrel w/flash hider & bayo lug, 3 posn tele-stock, A3 style upper with carry handle, lower marked :Colt AR-15 Tactical. Has anyone ever heard of Colt putting out a tactical version of the AR-15 and are lowers so marked pre-ban? The owner says the rifle is not a LE only AR-15. The owner is not the original owner and does not know if the rifle is in factory original condition or if the stock and upper were added later.
