Geissele Automatics Reliability Enhanced Bolt Carrier Group

Geissele Automatics Reliability Enhanced Bolt Carrier Group

The Reliability Enhanced Bolt Carrier Group is a 5.56mm full-mass, full-auto rated M16/M4 bolt carrier group built to exceed the military specifications.

Machined from a Carpenter 158 forging that has less impurities and is more consistent, the bolt is much stronger and greatly improved. Each bolt is individually high pressure tested and magnetic particle inspected.

The carrier features a properly torqued and staked, Chrome Lined, Nano coated, gas key. The cam pin is machined from an advanced tool steel also used to produce medical instrumentation known as H13, it is then coated with Nanoweapon (Chrome-Nitride) for maximum corrosion and wear resistance.

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.

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. Our 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.
