TacFire MAR011 AR15/M16 Mid-Length Stainless Steel Gas Tube with Pin

Building or rebuilding an AR-15? The TacFire MAR011 mid-length stainless steel gas tube is a reliable, no-fuss replacement or upgrade component that handles the critical job of routing high-pressure gas from your barrel to cycle the bolt carrier group. Whether you're assembling a new rifle from the ground up or swapping out a worn tube, this stainless steel construction delivers the corrosion resistance and durability you need for consistent performance in the field or at the range.

Made from hardened stainless steel, the MAR011 resists heat and corrosion, which means gas flows smoothly and predictably shot after shot. The tube pins directly into your front sight base or gas block—no special tools or gunsmithing required. That straightforward design also works with most pistol-length gas system configurations, giving you flexibility when sourcing parts or refining your build.

If you run an AR-15 or M16 platform and want a mid-length gas tube that won't nickel-and-dime you with premium pricing, the TacFire MAR011 balances solid materials with practical functionality. Keep one on hand as a spare, or grab one as part of a larger build. Installation is fast enough that you can handle it yourself in minutes.

Frequently Asked Questions

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

The TacFire MAR011 is designed for AR-15 and M16 platforms and is compatible with most pistol-length gas system configurations. Verify your gas block or front sight base accepts a pinned tube before ordering.

Do I need a gunsmith to install it?

No. The MAR011 pins directly into your front sight base or gas block. Installation requires no special tools or gunsmithing—just align and pin it in place.

Why stainless steel?

Stainless steel resists heat and corrosion, which protects the tube from fouling and degradation over time. This helps ensure consistent gas flow and reliable cycling across shooting sessions and varying conditions.

Is this a replacement or new-build part?

The TacFire MAR011 works as either. You can use it as a drop-in replacement for a worn or damaged gas tube, or source it as part of a complete new AR-15 build.
