Phase 5
The Phase 5 HEX2C Hex-2 buffer tube assembly is a purpose-built recoil management component for AR-pistol platforms. If you're building or upgrading an AR pistol, this black aluminum buffer tube handles the fundamental job of controlling bolt carrier movement and managing recoil impulse—critical for reliability, accuracy, and shootability in a compact platform. Phase 5 Weapon Systems brings rugged engineering to a part that most builders think about only once, then expect to work forever.
AR pistols demand components that can handle the unique geometry and spring loads of a shorter platform. The HEX2C's aluminum construction keeps weight down while maintaining the structural integrity necessary for reliable cycling across different ammunition and configuration loads. It's the foundation of your recoil system, working in concert with your buffer weight and spring to tune how the gun feels and performs.
Whether you're setting up a dedicated pistol-caliber upper, a short-stroke build, or a specialized AR pistol configuration, a quality buffer tube assembly ensures consistent lockup and smooth operation. This isn't flashy—it's straightforward engineering that lets you focus on the rest of your build.

| Material | Black Aluminum |
| Platform | AR-Pistol |
| Category | Buffer Tube Assembly |
The HEX2C Hex-2 buffer tube assembly is designed for AR-pistol platforms. Verify your upper and lower are configured for pistol operation before ordering.
Pistol buffer tubes are shorter and designed to work with the geometry and spring rates specific to AR-pistol uppers. They are not interchangeable with standard rifle tubes.
This product is the buffer tube assembly itself. Buffer weights and recoil springs are sold separately and should be selected based on your specific build configuration and ammunition choice.
