 Nitride Treated Barrels provide a very hard surface with excellent corrosion resistance. Nitriding has advantages in that it is a treatment of the steel itself instead of a secondary material which is added to the surface like chrome, this method offers superior corrosion resistance and accuracy then Chrome Lined Barrels

 Nitride Heat Treating  . During the process both nitrogen and carbon are liberated at the surface of the ferrous component. These nitrogen and carbon atoms form a compound layer at the surface and a deep diffusion zone beneath the surface. The compound layer provides lubricating properties to the surface and are extremely useful in areas where use of conventional lubricants are ineffective. Nitride Heat Treating Eliminates the need for chrome lining on Rifle Barrels. The barrier formed by this process is far better than any chrome lining process. The resulting barrier on  the lining of the barrel at end result is .001 in thickness. Improves accuracy and eases the cleaning process.
