Ar-15 Pistol Pigtail Gas Tube

The AR-15 Pistol Pigtail Gas Tube by Phase 5 Tactical is a specialized gas system component engineered for short-barreled AR pistol platforms where space and precision are non-negotiable. This component serves shooters who demand reliable ignition cycling in compact firearm configurations, particularly those running pistol-length gas systems that require optimized gas flow routing. Whether you're building a duty-ready AR pistol, a compact home-defense platform, or a specialized training rig, the Pigtail Gas Tube delivers the engineering solution that bridges gas delivery from the barrel to the bolt carrier group without compromise.

Manufactured by Phase 5 Tactical—a respected innovator in AR platform components—this gas tube is precision-machined to ensure consistent bore alignment and reliable gas impulse delivery. The design minimizes turbulence and dead zones in the gas path, critical for AR pistols operating under higher pressure curves relative to full-size rifles. The lightweight construction at just 0.08 lbs contributes to better handling characteristics without sacrificing structural integrity. Phase 5 Tactical's manufacturing standards ensure tight tolerances and repeatability, allowing the Pigtail Gas Tube to function reliably across varying ammunition types and suppressed or unsuppressed configurations.

This component is essential for AR pistol builders and law enforcement armorers managing compact weapon systems. Installation requires basic mechanical knowledge and integration with your existing gas block and carrier assembly during upper receiver build or maintenance. Compatibility spans most modern AR-15 pistol builds using standard M4 feed systems, though verification with your specific gas block is recommended. Veterans and tactical professionals who have run hundreds of hours on pistol-length systems understand that gas tube geometry directly impacts reliability—Phase 5 Tactical's Pigtail design reflects that operational reality, making it the choice for shooters who refuse to compromise.
