Lantac Ar15 Gas Tube Mid Length

The Lantac AR15 gas tube mid-length is a precision-manufactured replacement or upgrade component for mid-length gas system AR-15 builds. Built from stainless steel with a black nitrided finish, this gas tube delivers the corrosion resistance, durability, and clean-running performance that serious shooters demand in an AR platform rifle. Whether you're building a new rifle, upgrading an existing system, or replacing a worn tube, a quality mid-length gas tube is one of those foundational parts that pays dividends in reliability and longevity.

Nitriding is a hardening process that creates a wear-resistant surface far superior to bare stainless steel. The black nitrided finish resists heat erosion and corrosion from the harsh environment inside the gas system—where high pressures, extreme temperatures, and carbon fouling take their toll on uncoated parts. The result is a tube that runs cleaner and cooler than untreated alternatives, meaning less buildup, easier maintenance, and more consistent function over time. The finish also eliminates light reflection through your handguard, keeping your rifle low-profile and reducing unwanted glint in the field.

This tube ships complete with the gas tube roll pin needed for installation, so you have everything required to fit it to your receiver. Lantac's manufacturing is based in the USA, and the laser engraving marks on the part reflect that precision approach to every component. For mid-length AR builds—whether you're assembling a hunting rifle, duty gun, or range precision setup—this is a no-nonsense upgrade that improves durability without compromise.

Frequently Asked Questions

Will this gas tube fit my AR-15 build?

The Lantac gas tube is designed for AR-15 rifles with mid-length gas systems. Mid-length tubes are shorter than carbine tubes and longer than pistol-length tubes, positioning the gas port takeoff about midway down the barrel. Confirm your rifle's gas system length before ordering.

What's included in the box?

The tube comes complete with the gas tube roll pin needed to secure it to your receiver, so you have the essential hardware for installation in one package.

What does the black nitrided finish do?

Nitriding is a surface hardening process that dramatically improves wear, heat, and corrosion resistance compared to bare stainless steel. In the extreme environment of an AR gas tube—where temperatures spike and carbon fouling accumulates—nitriding keeps the tube running cleaner, cooler, and longer. The black finish also prevents light reflection through your handguard.

Is this tube made in the USA?

Yes, the Lantac AR15 gas tube is manufactured in the USA with precision laser engraving as part of Lantac's quality control process.
