  • Cold Hammer Forged for extreme durability and accuracy. Our precision cold hammer forging process produces an exceptionally straight and smooth bore finish with ideal land and grooves profiles, all of which are key to maintaining accuracy. The forging process also increases hardness and produces beneficial grain flow alignment which improves toughness.
  • Chrome Lined Chamber and Bore for excellent service life and resistance to corrosion. Our industry leading process was developed specifically to address the unique requirements of precision firearm barrels and includes 5 key improvements to ensure highly uniform and accurate results. This includes an electropolishing treatment before chrome lining.
