Lantac Mspec Intermediate Gas Tube

An intermediate-length gas tube for AR-15 rifles needs to be reliable, durable, and built to spec—and the Lantac M-Spec Intermediate-Length Gas Tube delivers all three. Built from 306 stainless steel, this tube is precision-manufactured to mil-spec standards and engineered to handle the demands of modern AR platforms. Whether you're building a new rifle, upgrading your current setup, or replacing a worn component, a quality gas tube is foundational to consistent function and longevity.

Lantac USA manufactures this gas tube domestically, ensuring tight tolerances and reliable performance shot after shot. The stainless steel construction resists corrosion and wear, so your gas system will stay in service through years of hunting, training, and competition use. Every tube ships complete with the gas tube roll pin you need for installation, so you won't need to source components separately.

The M-Spec designation means this tube meets military specifications for fit and function across standard AR-15 platforms. The laser engraving adds durability and traceability to the component. If you're assembling a mid-length or intermediate-length AR upper and want a gas tube that won't compromise reliability or value, Lantac's offering is a solid, American-made choice that performs without the premium markup.
