The Geissele Premium Mil-Spec Buffer Tube (H3) is ideal for carbine length gas systems and a 10.5” to 11.5” barrel. It is machined from 7075-T6 aluminum with a type III hardcoat anodized finish in Geissele’s DDC, making it an extremely durable and long lasting buffer tube. This reliable 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 a perfect fit for your AR-15 lower and ensures compatibility with most mil-spec diameter quality AR-15 stocks. The Geissele Super 42 buffer spring improves the function and reliability of your AR-15 pattern rifle by using three independent strands of wire to absorb energy and displace excess energy, decreasing the chance of spring failure. It features a 15 percent stronger average return force than the standard buffer spring, meaning it will assist in stripping rounds out of the magazine while operating a dirty weapon or when using steel-case ammo. Included in the package is a high-quality, mil-spec castle nut and end plate.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
