WTB: preban Colt front sight tower for HBar
I am looking for a used AR-15 front sight tower (with the bayonet lug) for a preban Colt 1/7 heavy barrel. It has to be preban because Colt changed the distance between the 2 drift pins (the pins that keep the front sight tower in place) on the postban front sight towers, to make it more difficult to install the bayonet lug on the postban guns. The distance between the drift pins on my barrel is 1.375" (1-3/8") center-to-center. If you have one for sale, then please e-mail me directly at email@example.com with a description of the condition, and your asking price. Thanks in advance.
