These barrels are extras from a Mk 15 Navy SEAL contract.  When we make a military run we always make some extras and are able to make them available on a one-time basis for our regular customers.   These are chambered in 50BMG, fluted, muzzle threaded 1″ x 14 TPI and Mil-Spec black oxide coated. Threaded 1.500″ x 12 TPI to fit a McBros/McMillan .50 caliber action. These are finished, drop-in ready barrels but the headspace will need to be checked by a gunsmith familiar with .50’s.
