CMMG

Overview

The CMMG AR-15 Gas Tube is crafted from polished stainless steel, providing a reliable pathway for gas to travel from the gas block back to the action, essential for semi-automatic cycling. With a mid-length gas system, this gas tube helps to optimize the balance of recoil and reliability, making it suitable for various shooting applications. This gas tube is frequently used in builds featuring a mid-length gas system and chambered in 5.56 NATO, making it a common choice for builders aiming for performance and smoother operation.

Stainless mid length clean look
Reviewed on April 24, 2026Verified with Build

Wanted a stainless tube to show off through my open top handguard. CMMGs mid length stainless steel polishes up nicely. Pin holes lined up correctly with my low pro block. Held up to a 14.5 mid length without any flame discoloration after a thousand rounds.
