This is an auction for a brand new Colt LE6920 5.56mm barreled upper that was professionally converted to Mk 18 specs by Specialized Armament. The barrel was originally a 16" 1:7 that they cut down, threaded, crowned, opened the gas port to 0.071" & completely refinished. This is exactly how Crane created the CQBR/Mk 18 for the Navy, by shortening the 14.5" M4 barrel. It took over 7 months for the work to be completed, but was well worth the wait. The barrel is date coded 06/16. It was refinished in Manganese Phosphate (finished in accordance with DOD-P-16232F Type M).

This auction includes:

1 Colt 10.3" LE6920 5.56mm barreled upper
1 Colt A2 Birdcage flash hider (installed)
