Your firearm or knife is an investment. When exposed to the harsh elements, wear and corrosion can cause damage and impede proper function. Our PVD coatings apply a micro-thin ceramic surface that achieves multiple objectives. First, it increases surface hardness, which protects the gun or blade from wear and corrosion. Second, the low friction property of the coatings increases lubricity, which prevents parts from jamming and seizing, ensuring optimal functionality. Third, a coating can change the appearance of a component to reduce glare for tactical use, or to give it a unique look to suit your personal style. Our coatings not only protect your investment, but can improve the durability, reliability, and appearance of your guns and blades.

Our PVD coatings can be applied to various types of firearms – revolvers, pistols, rifles, ARs. The process does not cause dimensional changes to the components, which makes it suitable for slides, barrels, frames, triggers, rifle bolts, BCGs, firing pins, suppressors and more.
