These list for $199.99 on Lothar Walther plus you get a Black Nitride finish. You couldn't do it yourself for cheaper!!
16 inch. Carbine gas system. 1x7(1x9 available also) Twist rate. LW19 Steel. Manufactured by Lothar Walther.
Black Nitride finish for durability and corrosion resistance.
These barrels are truly a cut above the rest! They start life at world class maker Lothar Walther. Made from LW19 bar stock, then drilled, contoured, chamber reamed and rifled at 1x7, 1x8, 1x9 twist and CNC lapped to provide fantastic out of the box accuracy.
On top of the quality that comes from a Lothar Walther barrel, these have undergone ferritic nitrocarborizing.
You now get the accuracy of a precision crafted barrel and the benefits of a black nitride finish.
Black Nitride has a lot of benefits. The surface of the steel normally has a rockwell hardness, hRc, of 42-46. After nitriding, the surface hardness goes up to 69-72. This gives greater durability to chrome lining, but unlike chrome lining you are not covering the lands and grooves with an uneven layer that can degrade accuracy.
Many of the top companies use Lothar's barrels,in their higher end uppers.
What is Black Nitride?
BLACKNITRIDE™, or Ferritic Nitrocarburizing, is the thermochemical that simultaneously diffuses nitrogen and carbon into the surface of ferrous metals. During the process, a two-part surface layer is formed, an outer iron nitride layer with a nitrogen diffusion layer below it.
During this treatment, nitrogen and carbon are absorbed by and diffused into the surface of the metal. Reproducible and uniform layers with a predetermined thickness will be formed on all areas of the metal. The result of this process is markedly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability.
Metal components treated with BLACKNITRIDE™ have increased wear-resistance, fatigue strength, corrosion resistance, lubricity and cosmetic appeal. Often replacing the more expensive processes of hard chrome or nickel plating, BLACKNITRIDE™ gives better corrosion protection.
Additionally, BLACKNITRIDE™ is commonly used as an alternative to high temperature conventional heat treatments such as carburizing and carbonitriding. Read more here: http://blacknitride.com/whatis.html
