EDIT: I am no longer looking for a 16" LW carbine upper. A member of the site had a LW Colt upper that I am purchasing.
I’m looking for a new or (lightly) used 16" upper, in a lightweight barrel format. I’m not looking for a BCG or rail system, just the basic upper.
A colt 6720 upper would be great, as would something from BCM.
Please contact me via PM if you have something you’d like to sell.
