Phase 5 HEX2C Hex-2 Buffer Tube Assembly Black Aluminum AR Pistol

The Phase 5 Weapon Systems HEX2C Hex-2 Buffer Tube Assembly delivers enhanced strength and reliability for AR pistol builds. This mil-spec buffer tube features Phase 5's signature hexagonal design that provides superior torque resistance and improved mounting stability over standard round tubes.

What Makes This Different

The hexagonal exterior profile prevents rotation under stress and provides multiple flat surfaces for enhanced wrench engagement during installation. Unlike standard buffer tubes that can slip or rotate when properly torqued, the HEX2C maintains precise alignment with the lower receiver. The 7075-T6 aluminum construction offers 40% greater strength than standard 6061 aluminum tubes while maintaining the same weight profile.

Key Features

• Hexagonal exterior profile prevents tube rotation and slippage
• 7075-T6 aluminum construction for maximum durability
• Mil-spec threading and dimensions for universal compatibility
• Type III hard coat anodized finish resists wear and corrosion
• Six-position length adjustment with positive lock engagement
• QD sling swivel attachment points integrated into design
• Compatible with all mil-spec AR-15 lower receivers and pistol braces

Field testing demonstrates consistent lockup and zero shift resistance even after thousands of rounds. The enhanced surface area of the hex design distributes stress more evenly across the receiver extension threads, reducing wear on both components. Law enforcement agencies report improved reliability in high-round-count training scenarios compared to standard buffer tubes.
