Detta är ett kit med Geisseles REBCG, Super 42-fjäder samt buffert i en vikt som du väljer själv.

REBCG

Detta är Geisseles vidareutvecklade BCG för AR-15. Bl.a. har man vidareutvecklat Carpenter 158-stålet (milspec kravet) i bolt head tillsammans med Carpenter-verken, något man är helt ensamma om. Detta är därför enda BCG:n som kan köpas med en C158+ legering. BCG:n är dessutom både försedd med längre rails och coatad. Allra bäst är det dock att läsa Geisseles egen beskrivning nedan.

Super 42-fjäder

Geisseles vidareutveckling av rekylfjädern. FJädern är "virad" likt den på MG42, vilket förlänger livslängden. Fjädern är även ca 15% starkare än en vanlig fjäder. Rekomenderas därför ej för .300 BO-laddningar. Finns endast i carbine length i detta kit, men sen relaterad produkt för ensam fjäder för dig som behöver en i rifle length.

Buffert 

Traditionell carbine length buffert, går att välja i H1, H2 eller H3. Om du är osäker på vilken vikt du ska ha, se tabell eller besök denna sida: CHOOSING A BUFFER WEIGHT FOR AN AR-15

Från tillverkaren:

REBCG

The Reliability Enhanced Bolt Carrier Group is a 5.56mm full-mass 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.

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 type 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.

Super 42-spring

The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.

Compared to the stock spring, The Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus, it removes the annoying spring reverberations (twang) heard and felt by the shooter through the buttstock. The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo.

NOTE:  The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubes/receiver extensions, a special rifle length version of our Super-42 is available on our website. 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.
