Pistol Buffer Tube

The Phase 5 Tactical Pistol Buffer Tube is a precision-engineered component specifically designed for AR-15 pistol builds. It is ideal for law enforcement, military, and civilian shooters who require reliable recoil management and structural integrity in high-stress environments. This buffer tube serves as the foundational interface between the lower receiver and the recoil system, ensuring firearm stability and cycling reliability.

Constructed with an emphasis on durability and precision machining, the Phase 5 Tactical design meets exacting military standards. This ensures consistent bore alignment and minimal tolerance stack-up within the receiver extension assembly. The internal geometry of the tube is compatible with standard AR-15 buffer springs and weights, while its external profile is optimized for lightweight configurations without sacrificing structural rigidity.

Operators building or upgrading AR-15 pistols will find this buffer tube essential for achieving repeatable and predictable performance. Its lightweight design, weighing just 0.48 lbs, minimizes overall system weight while maintaining the dimensional accuracy required for reliable bolt carrier group travel. This is critical for ensuring extraction and feeding reliability across diverse ammunition types and environmental conditions.
