AR 9mm Cal MIL-SPEC Buffer Tube Set (Anodized Grey)

Description

This AR 9mm Cal MIL-SPEC Buffer Tube Set is a complete assembly designed for builders requiring a six-position buffer tube configuration. Constructed from T6 Aluminum, the unit features an Anodized Grey Finish that provides corrosion resistance and a consistent aesthetic for the upper receiver area. The kit includes all necessary components for installation: a six-position buffer tube, end plate, castle nut, AR 9mm Cal Buffer, and a Chrome Silicon Coated Spring. The 9mm Cal Buffer weighs 8.2 oz, providing the specific mass required to manage the lower pressure and slower cycling speeds inherent to 9mm calibers compared to standard centerfire cartridges. Using the correct buffer weight is critical to prevent bolt bounce and ensure reliable operation in AR-15 platforms converted to 9mm. The Chrome Silicon Coated Spring ensures durability under repeated compression cycles, maintaining tension over the life of the buffer tube system. The Mil-Spec standard ensures compatibility with standard AR-15 lower receivers and pistol braces designed for Mil-Spec dimensions. The six-position length allows for precise adjustment of the buffer tube extension, accommodating various stock or brace configurations while maintaining proper headspace and spring compression. This set is designed for experienced builders who understand the specific mechanical requirements of 9mm conversion kits. It replaces the need to source individual components separately, ensuring that the buffer tube, spring, and buffer are matched for optimal function. The T6 Aluminum construction provides a balance of strength and weight, while the Anodized Grey Finish protects the metal surface from wear and environmental factors. This complete kit simplifies the build process by supplying all the critical lower receiver components needed to complete a functional 9mm AR-15 system.
