The C4V coating has been so popular we had to include it on our S2 BCG.
C4V (TiN) provides excellent wear resistance with a hardness of 2600 Vickers. C4V is a (PVD) coating (TiN), however one look at C4V and you will know this is not your average TiN. It has a coefficient of friction 0.4 and only 2 microns thick making it a major improvement over MilSpec. Our TacDriver Bolt made of SAE 9320 is coated IN Black Nitride
