Aim Sports XDB15RGAST AR-15 Gas Tube 15" Rifle Length Stainless Steel

The Aim Sports XDB15RGAST is a rifle-length gas tube built for the AR-15 platform. This 15" tube is precision manufactured from stainless steel for direct-fit installation on standard rifle-length gas systems.

Installed between the gas block and upper receiver, the gas tube routes combustion gases back to the bolt carrier group to cycle the action. Stainless steel construction provides corrosion resistance and long-term durability, making this a reliable component for completing a custom AR-15 build, replacing a worn or damaged tube, or maintaining an existing rifle.
