Product Description

TEXAS AR EXO Nickel Boron Bolt Carrier Group.

Why EXO? What are the benefits?

  • Replaces multiple coatings with one process, streamlining manufacturing
  • Provides total coverage and may not require final matching
  • Lower environmental compliance costs than hard chrome, anodizing and parkerizing
  • Not an exotic material or process
  • Repeatable, scalable, transferable technology
  • Can be applied to steel, aluminum alloys, titanium alloys

EXO Technology is featured in firearms, weapons and support systems used by the U.S. military and law enforcement and security agencies; for engine, powertrain, propulsion and wear components in the automotive, aerospace and maritime industries; in industrial pumping, mining and drilling applications. EXO Technology is appropriate for virtually any application where reduced friction, extended service life, enhanced performance and lower maintenance are desirable.

How does UCT’s EXO coating compare to conventional coatings?

UCT technology applies a nickel-boron (Ni-B) family of coatings to metal alloy surfaces. The properties of these coatings make them suitable for applications requiring high wear resistance, friction reduction, uniformity of dimensions on complex geometry, strong adhesion to substrates, and inherent solid lubrication. Corrosion inhibition is an added feature. Benefits include increased life cycle and decreased maintenance costs. 

We assemble our carriers by first using permatex NO.3D aviation 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. We use a crane-o-ring 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 multiple time to ensure the highest quality and backed by a lifetime warranty!
