UCT’S EXCLUSIVE EXO TECHNOLOGY
EXO Technology creates a competitive advantage for all kinds of components, because treated parts run dramatically longer and more accurately with less maintenance. Further, EXO greatly enhances heat dissipation, so treated products run far cooler than non-treated parts.
The EXO process is permanent, lasting for the entire lifespan of treated parts. A patented, nodular nickel-boron (NiB) surface treatment, EXO nucleates on the surface atoms of metals, becoming part of the metal rather than merely applied to the outside. In addition, the treated surface becomes harder than the substrate itself, eliminating the cost, weight and degradation problems of conventional hardened metals.
EXO Technology is featured in firearms, weapons and support systems used by the U.S. military and law enforcement and security agencies. EXO Technology is appropriate for virtually any application where reduced friction, extended service life, enhanced performance and lower maintenance are desirable.
BLACKNITRIDE™, or Ferritic Nitrocarburizing, is the thermochemical that simultaneously diffuses nitrogen and carbon into the surface of ferrous metals. During the process, a two-part surface layer is formed, an outer iron nitride layer with a nitrogen diffusion layer below it. During this treatment, nitrogen and carbon are absorbed by and diffused into the surface of the metal. Reproducible and uniform layers with a predetermined thickness will be formed on all areas of the metal. The result of this process is markedly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability.
Metal components treated with BLACKNITRIDE™ have increased wear-resistance, fatigue strength, corrosion resistance, lubricity and cosmetic appeal. Often replacing the more expensive processes of hard chrome or nickel plating, BLACKNITRIDE™ gives better corrosion protection at equivalent or lower costs. Additionally, BLACKNITRIDE™ is commonly used as an alternative to high temperature conventional heat treatments such as carburizing and carbonitriding.
The requirements for assembly of our Bolt Carrier Groups are much higher than most. Before assembling the gas key to the carrier, permatex NO.3D aviation is applied to form-a-gasket around the gas hole (per MIL-SPEC). Then Grade-8 hardware is used to attach the gas key, followed by properly staking per spec. When installing the extractor to the bolt, a crane-o-ring is inserted with the spring to insure proper ejection. Then high temperature grease is applied to the gas rings before inserting the bolt into the carrier, which allows for much smoother operation. These BCGs are inspected to the highest of standards, to insure a high quality product that is 100% reliable for our customer… PROUDLY MADE IN THE USA!
