INFAMOUS X FREAK COMPLETE FXL SS BLACK NITRIDE BOREMASTER INSERT + FXL BARREL KIT

Not just black for a cosmetic reason, the unique black tone of the Infamous® Freak® inserts are designed for increased durability and performance. 

Infamous® edition Freak® inserts are superior to standard Stainless Steel inserts due to the case-hardening process used to increase the inserts wear resistance, corrosion resistance and lubricity. Unlike anodizing or plating, the nitride process does not effect tolerances or weight of the insert and will never flake or peal.

The process used on the Infamous® inserts is a nitrocarburizing case hardening, known as quench polish quench nitriding, or by the brand names of QPQ®, Tufftride®, Tenifer® or Melonite®.

The surface properties of this treatment increases surface hardness by as much 300% over the base stainless material. Additionally the stainless base material takes on its characteristic black color.

Due to the nature of QPQ nitriding, there will be slight variance in the lasers ability to penetrate & bleach the color of the iron nitride surface. Lasering does not remove or reduce the surface treatment, it simply alters the color of the oxide itself.

The variance in color is not a result of layer thickness, or laser power/function.

The variance in color occurs due to the alignment of the iron particles in the material surface. Particles in the surface oriented away from the laser source will be less bleached of color than other particles that are parallel to the laser source. 

The resulting variance will yield a surface color varying from a silver to a gold hue, and is to be expected when lasering a material with this hardness & chemical composition.
