Description
This Bolt Carrier Group’s critical component, the bolt, is coated with an advanced Nickel Boron while it’s carrier is coated with a QPQ with a R.E.M polished surface. Β UTC’s EXO coated technology is a patented process that deposits a nickel boron (NiB) casting onto a metal surface giving that surface a permanent dry-lubricious material that is harder than the underlying substrate. Β This dry-lubricious surface reduces friction, and dissipates heat so well that your parts will run cleaner & cooler without the constant lubrication. Β Our BCG’s (Bolt Carrier Groups) are fully assembled, staked, and tested prior to shipment. Β Our complete Bolt is case hardened, shot peened and MPI (Magnetic Particle Inspection) tested to assure consistency.
NOTE: Please stay away from solvent based cleaners when maintaining your firearm and components.
