Expo Arms Stainless Steel Gas Tube – Carbine Length

Expo Arms Stainless Steel Gas Tube – Carbine Length

The Expo Arms Carbine-Length Gas Tube is a dependable replacement or build component for rifles using a carbine-length gas system. Constructed from corrosion-resistant stainless steel and supplied with a gas block roll pin, it provides the essential connection needed to route gas from the barrel’s gas block to the receiver.

Built for Carbine-Length Gas Systems

This 9.75-inch gas tube is designed for barrels with a carbine-length gas system, generally measuring approximately 7 inches from the barrel gas port to the front face of the upper receiver. It is suitable for compatible AR-15 and AR-308 platform builds that use the carbine gas-system configuration.

Stainless Steel Construction

Stainless steel construction offers strong corrosion resistance for long-term use in demanding rifle configurations. Whether you are assembling a new upper, replacing a damaged gas tube, or refreshing a hard-use rifle, this Expo Arms gas tube provides a straightforward, quality component for the job.

Includes Gas Block Roll Pin

A gas block roll pin is included to simplify installation and help secure the gas tube to a compatible gas block. This saves you from sourcing the small but essential installation component separately.
