Aero Precision Gas Tube Carbine Length Melonite Finish Black APRH100281C

The Aero Precision Carbine Length Gas Tube in Melonite finish is a critical component for any AR-15 or AR .308 builder or gunsmith. This stainless steel gas tube handles the fundamental job of directing high-pressure gases from your rifle's barrel back to the bolt carrier group—get it right, and your rifle cycles reliably; get it wrong, and you've got a malfunction waiting to happen. Aero Precision's reputation for precision manufacturing means you're getting a tube that's dimensionally accurate and finished to last, whether you're assembling a home-defense carbine, a competition rifle, or a field gun.

Carbine length is the most common configuration for modern AR builds, fitting standard carbine-length systems without the extra complexity or weight of longer tubes. The Melonite finish—a case-hardening process—provides superior corrosion resistance and durability compared to basic parkerizing or bluing, so your gas system won't degrade under hard use or adverse conditions. Because Aero Precision manufactures this component domestically, you're supporting US production while gaining confidence that tolerances and quality control meet the company's exacting standards.

Installation is straightforward: the tube comes with a roll pin included, so you have everything needed to secure it to your gas block once you're ready to assemble. Whether you're a first-time builder working through your first AR from the ground up or an experienced gunsmith stocking quality parts for multiple builds, this gas tube delivers the reliability Aero is known for without unnecessary frills or marketing noise.

Frequently Asked Questions

Will this gas tube work on my AR-15 build?

Yes. This carbine length gas tube is compatible with AR-15 rifles and AR .308 rifles running carbine-length gas systems. Verify that your build calls for carbine length (rather than mid-length or rifle length) before ordering.

What's the difference between Melonite and other finishes on gas tubes?

Melonite is a case-hardening finish that provides superior corrosion resistance, wear resistance, and durability compared to standard parkerized or blued finishes. It's particularly valuable on internal components like gas tubes that experience heat and pressure cycles and may be exposed to moisture or harsh conditions.

Do I get the roll pin, or do I need to buy it separately?

The roll pin is included with this gas tube, so you have everything needed to install it once your gas block is mounted.

Is this made in the USA?

Yes. Aero Precision manufactures this gas tube domestically.
