Bootleg AR-15 Mid Length Gas Tube - Stainless Steel (S/SBP-GTM-SBN)

The Bootleg AR-15 Mid Length Gas Tube in stainless steel is a critical upper receiver component built to handle the demands of precision shooting, competition, and field use. Whether you're assembling a new AR upper or refreshing a well-worn system, a quality gas tube is non-negotiable—it's the unsung workhorse that cycles your rifle under all conditions. Bootleg's stainless steel construction paired with Salt Bath Nitriding (SBN) coating delivers the durability and corrosion resistance serious shooters expect from a mission-critical part.

Mid-length gas systems strike a balance many shooters prefer: faster lock time than rifle-length tubes while smoother operation than carbine systems. If you're building or upgrading an AR-15 upper receiver, the gas tube you choose affects reliability, longevity, and how your rifle handles recoil impulse. Bootleg's engineering ensures consistent performance across suppressors, standard barrels, and various ammunition types.

The stainless steel material resists oxidation and corrosion, and the SBN coating provides uniform hardness and protection without the brittleness of some harder finishes. This is the kind of upgrade that pays dividends over hundreds of rounds—you install it once and forget about it. For shooters who demand parts that work as hard as they do, this tube delivers.

Key Features

• Stainless steel construction for superior corrosion resistance
• Salt Bath Nitriding (SBN) coating for uniform hardness and durability
• Mid-length gas system sizing for balanced performance
• Direct fit for AR-15 upper receiver assemblies

Frequently Asked Questions

What's the difference between mid-length, carbine, and rifle-length gas tubes?

Gas tube length determines how far down the barrel gas is tapped and affects cycle rate and recoil impulse. Mid-length is a popular middle ground—faster than rifle-length but smoother than carbine-length—and works well with a broad range of barrel lengths and ammunition.

Will this gas tube work with a suppressor?

This is a standard mid-length gas tube and will function with a suppressed rifle, though suppressor use may require tuning (adjustable gas blocks, buffer system changes, or ammunition selection) depending on your specific setup.

Is the stainless steel with SBN coating corrosion-resistant?

Yes. Stainless steel is inherently corrosion-resistant, and the Salt Bath Nitriding coating adds an extra layer of hardness and protection without the brittleness of some harder finishes, making it ideal for harsh or wet environments.

What's included?

You receive the gas tube only. Installation into your upper receiver assembly requires disassembly of the carrier group and removal of the existing tube.
