LBE Unlimited PBTBLK Pistol Buffer Tube Black AR-15 Platform

The LBE Unlimited PBTBLK Pistol Buffer Tube delivers reliable cycling performance for AR-platform pistol builds. This mil-spec diameter buffer tube ensures consistent bolt carrier group operation while maintaining the compact profile essential for pistol configurations.

What Makes This Different

Unlike standard carbine buffer tubes, the PBTBLK features a smooth exterior without carbine stock mounting positions, creating a cleaner profile specifically for pistol applications. The 7075-T6 aluminum construction provides superior strength-to-weight ratio compared to standard 6061 aluminum tubes. Internal dimensions meet mil-spec tolerances for compatibility with standard buffer springs and weights.

Key Features

• 7075-T6 aluminum construction for enhanced durability and corrosion resistance
• Mil-spec 1.148" internal diameter ensures proper buffer and spring function
• Type III hard coat anodized finish in matte black for long-lasting protection
• Smooth exterior profile without carbine stock attachment points
• Standard castle nut and end plate threading (1.185"-32 TPI)
• Compatible with all mil-spec AR-15 lower receivers
• Accepts standard carbine buffer springs and pistol buffers

Field testing demonstrates consistent cycling across various ammunition weights and powder charges. The hard coat anodizing resists wear from repeated buffer contact while maintaining dimensional stability under temperature extremes. This buffer tube performs reliably in competition shooting, law enforcement applications, and recreational use where compact AR pistol platforms are preferred.
