LanTac MSPEC Rifle +1 Gas Tube – AR-15 Rifle-Length Systems

The LanTac MSPEC Rifle +1 Gas Tube is designed for AR-15 rifle-length gas systems, providing reliable gas delivery from the gas block to the bolt carrier group. This gas tube serves as a direct replacement for worn or damaged OEM tubes, or as a component in custom AR builds. The +1 designation indicates an extended length to accommodate specific gas block configurations or handguard clearances that require additional tube length beyond standard rifle-length specifications.

Constructed from stainless steel with a corrosion-resistant finish, this gas tube is built to withstand sustained high-temperature cycling. Installation is straightforward for builders familiar with AR platform assembly—requires a gas tube roll pin and punch for installation into the gas block. The tube includes a roll pin for securing to the gas block.
