Unmodified Colt Model 01 (601) or 602 buffer tube with nice, original anodizing. Usually these have buggered threads but this one only has one slightly flattened thread that doesn't interfere with threading into the receiver. $180 shipped and payment in the form of USPS money order, Western Union money order or Certified Bank/Cashiers check. First "I'll take it" followed by a PM gets it.
