Armaspec Gas Tube Rifle Length – AR-15/AR-10 Rifle-Length Systems

The Armaspec Rifle Length Gas Tube is a direct replacement component for AR-15 and AR-10 rifles with rifle-length gas systems. Gas tubes are critical for cycling reliability—they channel propellant gases from the gas port to the bolt carrier group. This tube is essential for maintaining proper function whether you're replacing a worn or damaged tube or building a new upper receiver.

Constructed from stainless steel with a nitride finish for corrosion resistance and heat durability. This is a drop-in part requiring basic armorer-level familiarity: the gas tube installs into the gas block and secures with a roll pin. No professional gunsmithing required, but proper alignment and roll pin installation tools are recommended for a secure fit.
