Adams Arms AR-15 5.45x39mm Caliber Conversion Kit with 16" Barrel, Bolt, Flash Hider & 30-Round Magazine
The unique Melonite treatment applied to the barrel surface-hardens the metal, extending barrel service life by reducing friction in the bore and lessening bore surface wear. Melonite treatment produces an extremely hard, slick surface on steel that resists carbon adhesion and increases corrosion resistance, making for easier cleaning and maintenance.
