What Is Armor Guard and S-Line?

Armor Guard is a family of PVD and CVD coatings that have been engineered for use within the firearms industry. This range of processes and compositions allows us to match the best possible coating for each application, thereby ensuring the best performance based on the customer’s needs.

S-Line utilizes DCD, a proprietary low temperature coating process, to synthesize Boron Nitride (BN). This film has an extremely high temperature resistance combined with high lubricity, making it a particularly good coating for internal firearm components.
