Geissele Premium MIL-SPEC AR-15/M4 Black Buffer Tube Assembly w/Super 42 Combo H2 08-163B-H2

Improve your AR15 Carbine's function and reliability with Geissele's MIL-SPEC AR-15/M4 Black Buffer Tube Assembly and Super 42 Braided Wire Spring and Buffer Combo. The 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 spring utilizes an innovative design composed of three independent strands of wire - the same design used by the German MG42 Machinegun. The braided wire design operates like a harmonic damper as well as an energy absorber by allowing the springs to flex independently from each other. The result displaces energy which decreases the risk of spring failure, while also making the rifle more reliable. In comparison to the standard spring, the Super 42 Braided Wire Spring is less likely to lose length and force over time, and also eliminates the irritating spring reverberations heard and felt through the buttstock. In addition, the Super 42 Braided Wire Spring's return force is roughly 15% stronger than the standard spring, which enhances the carbine's ability to strip cartridges out of the magazine when the weapon is dirty or when using steel case ammunition.
