AR10/AR15 Gas Tube Rifle Length

Rifle Length Gas Tube for AR-Platform Builds

This rifle-length gas tube is built for AR-platform systems that use a rifle-length gas configuration, where the gas port sits farther down the barrel. The longer travel distance affects how and when the system cycles, which is why matching gas tube length to your barrel's gas port location is an essential step in any build. Made in the USA, it routes gas from the gas block back toward the upper receiver as part of the cycling process.

It suits builders assembling complete uppers as well as those replacing or upgrading an existing gas system component. Before ordering, confirm that the rifle-length designation matches your barrel and gas block setup, since gas tube lengths are not interchangeable across systems.

If your barrel uses a shorter gas port location, compare the mid-length gas tube, carbine-length gas tube, or pistol-length gas tube to match your configuration.
