Corrosion-resistant, Heat-hardened, and Built to Last
The STNGR Black Nitride Gas Tubes are engineered for long-term durability and consistent gas delivery in AR-15 and AR-10 platforms. Precision-machined from mil-spec 304 stainless steel, each gas tube is treated with a black nitride finish for superior corrosion resistance, heat tolerance, and reduced fouling in comparison to traditional stainless gas tubes. Whether you’re upgrading components or completing a new rifle, STNGR gas tubes deliver reliable, maintenance-friendly performance designed to stand up to high-volume shooting and harsh conditions.
