Bravo Company Mil-Spec Carbine Receiver Extension | Buffer Tube | 6 Position

The Bravo Company Mil-Spec Carbine Receiver Extension | Buffer Tube | 6 Position is engineered to provide a rock-solid foundation for collapsible stock assemblies on AR-15 carbines. Machined from 7075-T6 aluminum and finished with MIL-A-8625F Type III Class 2 hard coat anodizing, this receiver extension meets full mil-spec standards for strength, wear resistance, and durability in the harshest conditions.

This tube features six precision-machined length-of-pull adjustment positions to accommodate a variety of shooter preferences and body types. Its true mil-spec diameter ensures a snug fit with compatible stocks, eliminating the wobble seen in commercial-spec buffer tubes. Internal threading is precisely cut to guarantee proper alignment and reliable installation with your lower receiver.

Important Fitment Note: This receiver extension includes reinforcement ribs near the rear of the tube. Due to this design, some stocks may not fully collapse all the way to the end plate. Most commonly used stocks will still function reliably, but users should be aware of this spacing difference when selecting a stock for tight or minimal overall length configurations.

The BCM 6-position buffer tube is compatible with standard carbine buffer systems, castle nuts, end plates, and mil-spec carbine stocks. It is ideal for duty-grade builds, defensive carbines, and high-end custom AR-15s requiring dependable performance and rugged construction.
