Reliability Enhanced Bolt Carrier and Gas Key

The Reliability Enhanced Bolt Carrier is a 5.56mm full-mass, full-auto rated M16/M4 bolt carrier group manufactured in Geissele’s state-of-the-art manufacturing facility in North Wales, PA. The carrier features a properly torqued and staked, Chrome Lined, Nano coated, gas key. The extended upper rails on the carrier also provide much greater stability and dramatically increase feeding reliability. The Carrier is coated with Nanoweapon for maximum corrosion and wear resistance.

Reliability Enhanced Bolt Carrier and Gas Key Specification

Nanoweapon is a family of coatings similar to DSL (Durable Solid Lubricant) that was developed by Picatinny Arsenal (US ARMY ARDEC), and is only available exclusively from Geissele Automatics. Their engineers worked for over 3 years with the research and development company that worked with Picatinny to develop the coating in order to fine tune it into what it is today, making it the pinnacle of coatings for firearm components. No other coating on the market can provide the same level of corrosion, wear, and abrasion resistance as Nanoweapon. The coating is applied at low temperatures so it does not affect the metallurgy of the part, and has a surface hardness equivalent of 82HRC. At that hardness, it is harder than sand, easily rejecting carbon and making cleaning a breeze, on top of allowing the firearm to operate normally with less lubrication.
