| I have been looking for a 14.5" lightweight barrel too. I see the 6520 uppers once in awhile on gunbroker. And you can try Fidelis Firearms too, they sell a lot of Colt uppers. They have (2) 16" lightweight uppers right now, but they both have the fixed carry handle. And you can also call Specialized Armament, I am sure they can get anything you want. I plan on buying a fixed handle upper and changing the receiver out with a flat-top receiver if I can't find just a barrel. |
