LANTAC USA GT-I6003 AR-15 Intermediate Length Gas Tube - Black Nitride

The LANTAC USA GT-I6003 is an intermediate length AR-15 gas tube precision manufactured from stainless steel extruded tubing and finished in a durable black nitride coating. Intended for AR-15 platforms running between mid and rifle length, this tube measures 13.660 in long and delivers reliable gas flow for cycling the bolt across the 5.56 NATO / .223 Remington range.

The black nitride finish is applied for enhanced corrosion resistance, heat tolerance, and erosion resistance compared to standard untreated gas tubes, allowing the part to run cooler and cleaner under sustained fire. Each tube is laser engraved with the LANTAC USA brand marking and ships complete with the matching gas tube roll pin needed for installation in a standard AR-15 upper receiver.

Whether you are building a custom carbine or replacing a worn factory gas tube, the GT-I6003 is a high-quality drop-in component designed to withstand the heat and pressure of regular AR-15 use.
