Selling a lightly used Triarc 13.9" complete upper receiver. The upper is a complete build straight from Triarc and has not been modified. Comes with Triarc's 13.9" Track 2.0 barrel with a pin and weld HUXWRX flash hider to meet the overall 16.1" length. This is the shortest you can get without going into SBR territory. The BCG is Triarc's NP3 finish complete BCG. Will come with a PRI Gas Buster Charging handle (shows a Geissele charging handle in the pictures but will come with the PRI Gas Buster).   

Let me know if you have any questions. Price is firm. Open to trades but not looking for revolvers, shotguns, or bolt guns. Looking for Glock 34 Gen 5 MOS or Glock 17 Gen 5 MOS, Canik Rival SFX, CZ-75 SP-01, etc etc.
