I often wonder what meathod of metal hardening Rock River uses on their parts? I heard there is a real good process called "Induction Forging" which is used to the firearms industry. Whereas metal is heated by Induction meathod and pounded into shape. I love to hear stories of no re-melted steel, "Certified Steels" and great hardening as it relates to Quality Control! It sure looks like Rock River uses some type of Robotic Polishing Stations to put the final finish. Their finish is one of the best I have seen.
