Geissele AR15/M4 Premium Mil-Spec Buffer Tube Assembly w/ Super 42 H1 7075-T6 DDC
The Geissele Premium Mil-Spec Buffer Tube is machined from quality 7075-T6 Aluminum and finished in Type 3 Hardcoat 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 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 are a high-quality, mil-spec castle nut and endplate.
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.
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.
