We are proud to introduce LiFe, the next generation of ferritic nitrocarburizing.  The LiFe process is not just another trademark for decade’s old technology, but an evolutionary method of ferritic nitrocarburizing and oxidizing simultaneously. (US7238244 B2 Patent)

 The LiFe process results are unparalleled on firearms components, enhancements include:

    Increased hardness and wear resistance
    Increased corrosion resistance
    Lower coefficient of friction
    Integral complex oxide layer
