The Geissele Premium Mil-Spec Buffer Tube is machined from quality 7075-T6 Aluminum and finished in Type 3 Hardcoat Anodize. This rigid and durable buffer tube conforms to all mil-spec standards and features 6 stock positions. This carbine length and mil-spec diameter Premium Buffer Tube is made in the USA and weighs in at 3.7oz, making it the perfect fit for your AR-15 lower and ensuring compatibility with most mil-spec diameter quality AR-15 stocks. Included in the package is a high-quality, mil-spec castle nut and end plate.
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.
ANODIZE VARIATIONS & DIFFERENT LIGHT SOURCES
You will notice that some of these will have wildly different shades of colored anodizing, and they look wildly different depending on the light source! Why would we even consider selling parts like this? The answer is there is absolutely nothing we can do to make colored anodizing consistent for the superior type of anodize we use.
NOTE: In the images above you will find a collection of these parts to show you a range of what you may receive. Also shown are images of the same exact parts taken under different light sources.
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. 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.
