I am wanting a 12.5, 14.5, or 16in Barrel for an XM177 Project. No M4's or Dissys but any profile (HBAR, Lightweight, etc.) is OK. Preban or Postban is ok, also exterior condition can be rough as this is going to be reprofiled, threaded, and refinished. Price is king. Let me know what you have, can also be on an A1 or A3 upper as I have use for both of those. Thanks!
