Stainless Steel AR-15 Gas Tube
Luth-AR gas tubes are quality, US-made pieces that serve as excellent replacements or components for a new upper build. These gas tubes come in four lengths to fit a wide variety of AR-15 barrels, and include a gas tube roll pin to install in a low profile gas block. Be sure to check the specifications of your barrel to make sure you make the correct selection.
