One Horse OH-GT03 AR-15 Mid-Length 11.7" Gas Tube - Stainless Steel

The One Horse OH-GT03 is an AR-15 mid-length gas tube constructed from stainless steel for durable, corrosion-resistant performance in standard Mil-Spec upper receivers.

Built for use in mid-length gas system AR-15 builds, the OH-GT03 measures 11.7" overall and pairs with standard barrels and low-profile gas blocks to deliver softer recoil, smoother cycling, and improved reliability over carbine-length configurations.

Its stainless steel construction resists heat, gas, and fouling while maintaining the precise alignment a bolt carrier group needs for consistent function. Whether you are assembling a new AR-15 from a stripped upper or replacing a worn factory tube, the One Horse OH-GT03 is a straightforward drop-in upgrade for any standard mid-length platform.
