Geissele Reliability Enhancement Kit, H2 5.56mm


SKU: 05-492-H2 Category:


The Geissele Reliability Enhancement Kit includes the Geissele Reliability Enhanced Bolt Carrier Group and the Geissele Super 42 Braided Wire Buffer Spring & Buffer in your choice of H1, H2 or H3 configuration for 5.56mm AR-15 pattern rifles. The Geissele REK is the culmination of a many years of extensive testing and fine tuning to bring you the most reliable operating system upgrade you can make to your carbine.

The Reliability Enhanced Bolt Carrier Group 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 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.
