AERO GAS TUBE RIFLE LENGTH MELONITE

The Aero Gas Tube Rifle Length Melonite is a direct impingement gas tube built for AR-15 and AR-308 platform rifles that demand reliability and longevity. Whether you're assembling a new upper, replacing a worn tube, or upgrading to a more durable finish, this tube combines Aero's proven design with melonite coating for enhanced corrosion resistance and a finish that stands up to hard use in the field or at the range.

Melonite treatment is a salt-bath nitriding process that creates a dark, corrosion-resistant surface—tougher than plain stainless steel and more protective than standard finishes. That matters if your rifle sees moisture, temperature swings, or extended storage between trips. The tube comes with a roll pin for secure installation, and it's manufactured in the USA, so you know what you're getting.

Aero offers this rifle-length gas tube in four different lengths to match your barrel and handguard setup, so measure before you order and make sure you're getting the right fit for your build. It's a simple component but a critical one—the gas tube directs combustion gases back to cycle your bolt carrier group, and quality here translates to reliable function when it matters.

Frequently Asked Questions

Will this gas tube fit my AR-15 or AR-.308 build?

This tube is compatible with both AR-15 and AR-.308 direct impingement rifles. It's available in four rifle-length sizes: 6.75", 9.75", 11.75", and 15.25". Measure your barrel length and handguard setup to select the correct length for your platform.

What's the advantage of the melonite finish?

Melonite is a salt-bath nitriding process that hardens the surface and provides excellent corrosion resistance—ideal if your rifle will be exposed to moisture, humidity, or stored for extended periods. It's tougher and more protective than standard finishes while maintaining a dark, professional appearance.

Does it come with everything I need to install it?

Yes, the roll pin required for installation is included with the tube. You'll just need basic tools and knowledge of your upper assembly to swap it in.
