Guntec USA AR-15 Mid-Length Gas Tube - Stainless Steel

The Guntec USA MTUBE is a mid-length gas tube designed as a direct replacement or upgrade part for the AR-15 platform. Machined from 304 stainless steel, this tube is built to resist corrosion under hard use and to deliver consistent gas flow to the bolt carrier group across thousands of rounds.

The mid-length gas system positions the gas port further down the barrel than a carbine-length setup, which reduces felt recoil and muzzle rise while still reliably cycling a wide range of 5.56 NATO and .223 Remington ammunition. At approximately 12.7" overall, this tube is intended to pair with a standard mid-length gas block on an AR-15 upper receiver and installs as a straightforward drop-in component.

Guntec USA produces the MTUBE in the United States, making it a clean replacement for a worn or upgraded mid-length gas system.
