LanTac Nitrided Gas Tube Rifle+1 Features The LanTac Nitrided Gas Tube is precision manufactured from a stainless steel extruded tube built to hold tight tolerances for reliable cycling in rifle length plus one AR-15 gas systems. The black nitride finish adds meaningful corrosion resistance along with improved heat and erosion resistance compared to standard untreated tubes a benefit for rifles that see sustained high round count use. Nitrided tubes also tend to run cleaner and cooler than untreated steel reducing carbon buildup inside the gas system over time. This combination of treatment and material gives the tube a service life well beyond typical factory parts. Beyond performance the black finish eliminates the light reflection off bare metal that can otherwise be seen through gaps in the handguard keeping the rifle s appearance clean and low profile. The tube ships complete with a gas tube roll pin so installation does not require sourcing additional small parts. Manufactured entirely in the USA the LanTac Nitrided Gas Tube reflects a commitment to domestic production and quality control. For sale at GrabAGun it is a straightforward upgrade for any AR-15 builder looking to improve gas system durability.
