Geissele Premium MIL-SPEC AR-15/M4 Black Buffer Tube 08-162B

Geissele Premium MIL-SPEC AR-15/M4 Black Buffer Tube 08-162B is machined from 7075-T6 aluminum and finished in Type III hardcoat anodize, also available in Geissele's DDC and ODG color options. This rigid, durable buffer tube conforms to all mil-spec standards and features 6 stock positions.

This Geissele Buffer Tube runs carbine length at mil-spec diameter, made in the USA and weighing 3.7 oz. That weight and diameter combination is what makes it the perfect fit for an AR-15 lower, ensuring compatibility with most mil-spec diameter quality AR-15 stocks rather than the narrower commercial-spec tubes some manufacturers still ship. A high-quality mil-spec castle nut and end plate come included in the package, so there's no need to source those separately.

This M4 Buffer Tube doesn't come bundled with a spring or buffer - it's the tube itself, giving builders the flexibility to pair it with whatever internal spring and buffer weight combination actually fits their gas system and recoil preferences, rather than being locked into a preset kit.
