Looking to buy a limited production Colt M4 16inch SOCOM heavy barrel in new or like new condition. This is the barrel that came on the limited production 1 of 300 Colt LE6920HB M4 carbines that SAW had for sale awhile back. I would also consider buying a complete upper assembly depending on condition and price. I am NOT interested in any other types of Colt barrels or any other companies version/clone of the Colt M4 16 inch SOCOM barrels. I have cash or Colt M4 parts to trade. Please contact me via IM or e-mail. Please do not post here as I dont want to babysit a thread.
