The Aim Sports Rifle-Length AR-15 Gas Tube (brand part number XDB15RGAST) is a precision-manufactured stainless steel gas tube sized for rifle-length gas systems, the setup typically found on 20-inch-barrel AR-15 rifles. It routes propellant gas from the gas block back to the bolt carrier group to cycle the action, and a properly sized, corrosion-resistant tube is essential for reliable function. Aim Sports machines this tube to spec from stainless steel so it holds up to heat cycling and repeated use without the flaking or rust issues that can plague lower-quality tubes. It’s an easy, affordable way to replace a damaged or bent gas tube or to complete a rifle-length gas system build.
