LBE Unlimited AR Gas Tube – Rifle Length

The LBE Unlimited AR Gas Tube in rifle length is a direct replacement component for AR-15 and AR-10 pattern rifles with rifle-length gas systems. Gas tubes are critical to reliable cycling—they channel combustion gases from the gas port to the bolt carrier group. This part is essential when building a new upper receiver or replacing a worn, damaged, or corroded original tube.

Constructed from stainless steel with a mil-spec diameter and finish, this gas tube is designed for drop-in installation. It includes a roll pin for secure attachment to the gas block. While installation is straightforward for those familiar with AR platform maintenance, proper alignment and roll pin staking require care to ensure safe, reliable function.
