Lantac Rifle-Length Nitride Gas Tube — AR-15

Precision-manufactured for AR-15 rifle-length gas systems, this Lantac gas tube is produced from stainless steel extruded tubing and finished with a black nitride coating for improved corrosion, heat and erosion resistance. The nitride treatment also helps the tube run cleaner and cooler compared with untreated tubes, and the black finish reduces light reflection through the handguard. The tube ships complete with the gas tube roll pin and carries a manufacturer laser engraving noting it was produced in the USA.
