JG 5.56 NATO High Polished DLC BCG – Black

Jacob Grey Firearms DLC (Diamond-Like Carbon) coatings have been widely successful in the aerospace industry. Jacob Grey’s carbon-based coating has extreme hardness due to the diamond crystal structure and is soft and lubricious due to the graphite crystal structure. Our DLC coatings are generally amorphous (without typical crystal structure). The properties of DLC coatings in terms of increased hardness, coefficient of friction, roughness, adhesion level, load carrying capacity, resistance to humidity influenced degradation, fatigue tolerance, etc. can easily be explained as beneficial within the firearms industry. But with its sleek and stylish looks and its ability to withstand carbon buildup and fouling, why would you want anything less inside your firearm. Available in Jacob Grey’s signature DLC black color Lethal Black.
