Geissele Premium MIL-SPEC Buffer Tube Assembly with Super 42, H1, 7075-T6, AR-15/M4 – DDC

The Geissele Premium Mil-Spec Buffer Tube is machined from high-quality 7075-T6 Aluminum and finished in Type 3 Hard Coat Anodize, available in Black or Geissele’s DDC. This rigid and durable buffer tube conforms to all mil-spec standards and features 6 stock positions. This carbine-length, mil-spec diameter Premium Buffer Tube is made in the USA. It weighs 3.7 oz, 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 likelihood of spring failure and enhances the reliability of your AR-15.

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 eliminates the annoying spring reverberations (twang) 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 from the magazine when operating with a dirty weapon or when using steel-case ammunition.

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, which could prevent the rifle from functioning correctly.
