Wilson Combat AR-15 Stainless Steel Gas Tube - 9.75"

A Wilson Combat AR-15 stainless steel gas tube is a critical internal component for any modern piston or direct-impingement rifle build. This 9.75-inch carbine-length gas tube is engineered for use in standard AR-15 platforms and meets military specifications, making it a reliable choice if you're upgrading or rebuilding a carbine-length upper receiver. Wilson Combat manufactures components to government contractor standards, so you're getting the same precision and durability demanded by professional users and competition shooters.

Gas tubes see real stress during firing—they route high-pressure combustion gases back to cycle the bolt, and even slight wear or dimensional error can affect reliability and accuracy. A quality replacement matters, especially if your rifle has thousands of rounds downrange or you're assembling a new upper from parts. Stainless steel resists corrosion and holds up to repeated cleaning and harsh environments better than standard steel, an advantage for hunters and shooters who run their guns hard in wet or dusty conditions.

This is a tube-only component—you'll need the gas block itself and any pins or hardware separately. Installation requires disassembly of your gas system and is typically a job for someone comfortable with AR armorer work, though any competent gunsmith can handle it in minutes. If you're rebuilding an upper, replacing a worn tube, or tuning your rifle's gas system, this Wilson Combat part gives you a mil-spec foundation without the guesswork of generic surplus tubes.

Frequently Asked Questions

Will this gas tube fit my AR-15 upper?

This carbine-length gas tube is sized for AR-15 platforms and M16 configurations using a carbine-length gas system. Confirm your upper is carbine-length (not mid-length or rifle-length) before ordering. The tube is the component only; you'll need a compatible gas block to secure it.

What comes in the box?

You receive the gas tube only. Pins, the gas block, or any other hardware must be sourced separately.

When would I need to replace my gas tube?

Gas tubes wear or corrode over time, especially if your rifle gets heavy use or exposure to wet conditions. If you're rebuilding an upper, upgrading components, or troubleshooting reliability issues, a quality replacement tube like this Wilson Combat part is a smart foundation.

Is this compatible with piston-driven uppers?

This is a standard direct-impingement carbine-length gas tube. Verify compatibility with any custom or piston-system configurations before purchase, as those setups may require different geometry.
