CMMG Mid-Length Gas Tube with Roll Pin

The CMMG Mid-Length Gas Tube with Roll Pin is an essential component for AR-15 platform rifles equipped with mid-length gas systems. This precision-engineered part is designed to direct high-pressure gas from the barrel into the bolt carrier group, ensuring reliable cycling of the action under various conditions. Whether for duty, competition, or tactical use, a quality gas tube is crucial for consistent performance across different ammunition loads and environments.

Manufactured by CMMG, this gas tube is built to exacting tolerances, which helps maintain proper gas port alignment and minimizes tolerance stack-up that could compromise reliability. The mid-length design optimizes gas dwell time for barrels ranging from 14.5" to 16", effectively reducing bolt carrier velocity while ensuring dependable function and enhancing the longevity of components. The included roll pin secures the gas tube to the barrel extension, preventing any unwanted rotation or separation during firing.

CMMG gas tubes are trusted by operators and gunsmiths for AR-15 build projects where precise gas system tuning is critical. Installation is straightforward, requiring the removal of the barrel extension and alignment of the gas tube with the barrel port before securing the roll pin. This component is compatible with standard AR-15 mid-length systems, making it an ideal choice for those looking to enhance their rifle's performance.
