Pistol-Length Gas Tube for AR-Pattern Rifles

This pistol-length gas tube represents a critical component in the gas system of your AR-pattern rifle. Properly sized and finished, it ensures reliable cycling and consistent performance across a wide range of shooting applications.

Key Features

• Pistol-length configuration optimized for shorter-barreled AR builds
• QPQ finish provides superior corrosion resistance and durability
• Mil-spec compatible fits standard AR-pattern upper receivers
• Precision manufactured for reliable gas system function

What You Need to Know

The gas tube is the conduit through which expanding gases from the fired cartridge travel from the barrel to the bolt carrier group, driving the action. A properly functioning gas system is essential for reliability.

This component is ideal for builders constructing or upgrading AR-pattern rifles for competition, duty use, or personal defense. The QPQ finish—a salt-bath nitriding process—hardens the steel surface while maintaining dimensional accuracy, resulting in a part that resists corrosion and wear.

Compatible with standard mil-spec AR platforms, this gas tube integrates seamlessly into most builds without modification.
