Geissele Reliability Enhancement Kit

The Geissele Reliability Enhancement Kit includes the Geissele Reliability Enhanced Bolt Carrier Group (REBCG) 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 kit is manufactured in Geissele’s state of the art facility in North Wales, PA.

The REBCG is a 5.56mm full mass, full auto rated M16/M4 bolt carrier group. The carrier is machined from mil-spec 8620 steel, and features a properly torqued and staked, chrome lined, gas key. The cam pin is machined from an advanced medical steel typically used to produce medical instrumentation known as H13, it is then coated with Nanoweapon 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 maxium corrosion and wear resistance.

The Geissele Stressproof Bolt is made from Carpenter 158. Since Geissele wanted to take it to the next level, Geissele’s engineers worked directly with the Carpenter Steel metallurgists in Reading PA, to produce a special heat of material known as Carpenter 158+. This material is cleaner with less impurities, ultimately making it stronger and more consistent. Using the same process used to produce upper and lower receivers, a forged bolt manipulates the grain structure of the metal and yields a bolt capable of 5 times the life of a mil-spec bolt. Each bolt is then rigorously inspected, high pressure tested, mag particle inspected and coated with Nanoweapon for maximum corrosion and wear resistance.
