Reliability Enhanced Bolt Carrier Group – 5.56mm

The Reliability Enhanced Bolt Carrier Group is a 5.56mm full-mass, full-auto rated M16/M4 bolt carrier group. 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. The Geissele Stressproof Bolt is made from Carpenter 158+. This material is cleaner with less impurities, ultimately making it stronger and more consistent. The 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.
