Parallax Tactical's Titanium Nitride Bolt Carrier Group is an 8620 steel bolt carrier that has been coated using a technique called cathodic arc PVD, or physical vapor deposition. This bolt carrier group is completed with a Nickel Boron coated Carpenter 158 bolt and 4130 steel cam pin.
TiN is an extremely hard ceramic material, often used as a coating on titanium alloys, tool steel, stainless steel, carbon steel and other metallic components to improve the substrate's surface properties. Common applications include aerospace parts, military components, medical implants, cutting tools, industrial parts, manufacturing dies / molds and dental and orthodontic appliances. TiN is a beautiful gold color and is often used as a wear resistant alternative to elemental gold plating.
This carrier has a matte gold finish, as all the major components were Titanium Nitride treated directly.
The Carpenter 158 steel is also Magnetic Particle Inspected!
