Geissele Automatics Reliability Enhancement Kit for AR-15 Rifles
(Model: H2 Buffer)

Product Description

Features

• Heavy duty braided steel construction
• Independent strands of wire act as a harmonic dampener to eliminate the "twang" sound heard when firing an AR
• Stronger than average spring return force assists in stripping rounds from the magazine as well as operating with a dirty weapon
• Wires flex separately from one another to help displace energy for softer feeling recoil
• 8620 steel construction with a chrome lined gas key and bolt recess in accordance with MIL-spec standards
• Bolt is produced out of Carpenter 158+ in accordance to meet and exceed MIL-spec standards
• Carrier is coated with Nanoweapon (Chrome-Nitride) for maximum corrosion and wear resistance
• Improved reliability and longevity

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.

Manufactured in Geissele's state-of-the-art manufacturing 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 (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, however this is not your typical material spec d by the US Government. Since Geissele wanted to take it to the next level, our 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. We did not stop there, we decided to forge the bolt. 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.

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.

Manufacturer: Geissele Automatics

NOTE: The Super 42 is not compatible with rifle length or A5 buffer tubes/receiver extensions. We do not recommend the Super 42 with 300 Blackout subsonic ammunition. The Super 42 Spring may be too powerful and not allow the rifle to function properly.
