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

Description

This is Cal MIL-SPEC Buffer tube set engineered for AR-9mm platforms, constructed from T6 Aluminum and finished with an Anodized Blue coating. The kit provides a complete assembly for the lower receiver, replacing standard Buffer Tube with a system optimized AR 9mm Cal buffer weights and spring dynamics. The six Position buffer tube allows for precise stock adjustment, accommodating various stock configurations while maintaining Mil-Spec diameter compatibility for standard buffer tube accessories. The set includes all necessary hardware for installation: an End Plate, a Castle Nut, AR 9mm Cal Buffer, and a Chrome Silicon Coated Spring. The 9mm Cal Buffer weighs 8.2 oz, a specification critical for managing the lower recoil impulse and ensuring reliable cycling in 9mm conversions where standard carbine buffers may overdrive the system. The Chrome Silicon Coated Spring is selected for durability and consistent tension in high-cycle applications. Material specifications are defined as T6 Aluminum for the tube body, offering a balance of strength and weight reduction compared to steel alternatives. The Anodized Blue Finish provides corrosion resistance and a distinct visual identifier for the build. The product is designed for direct installation into Mil-Spec lower receivers, ensuring proper fitment with standard AR-15 stock interfaces. This kit is intended for use by experienced builders familiar with AR platform mechanics and 9mm conversion requirements.
