Centurion Mk12 5.56 Barrel

Stripped barrels will now come in shiny stainless (AS PICTURED)

These are Crane Spec. MK12 barrels. These barrels are the result of tens of thousands of dollars in development done by the U.S. government to give our Special Operations guys the best weapon system they can have. We have spoken with many riflemen who have used these barrels and carried them in combat and have found unanimous satisfaction with their reliability and accuracy. Best option for long range, high precision shooting.
