Santan Tactical AR-15 Mid-Length Gas Tube - Nitride Finish

The San Tan Tactical AR-15 mid-length gas tube with nitride finish is a straightforward replacement or upgrade component for modern piston-driven AR platforms. Whether you're rebuilding a rifle, swapping out worn parts, or tuning your gas system for reliability, a quality mid-length gas tube is essential to consistent function. This nitride-finished tube is built to handle the demands of regular shooting—hunting, competition, training, or duty use—without cutting corners on material or manufacturing.

Mid-length gas systems sit between carbine and rifle-length designs, offering a balance of dwell time and impulse control that many shooters prefer for general-purpose rifles. The nitride finish provides corrosion resistance and a hard, durable surface that stands up to the heat and carbon cycling of repeated fire. San Tan Tactical's attention to manufacturing precision means this tube will fit and function reliably in compatible AR platforms, giving you confidence in the performance of your gas system.

This is the kind of part that doesn't draw attention—until you need one. If you're doing an AR build, replacing a damaged tube, or refreshing an older rifle's internals, a quality mid-length gas tube like this one is a smart choice that won't let you down.

Frequently Asked Questions

Will this gas tube fit my AR-15?

This is a mid-length gas tube designed for AR-15 rifles with mid-length gas systems. Verify your rifle's gas tube length before purchasing—carbine and rifle-length systems use different tube sizes and are not interchangeable.

What's the advantage of the nitride finish?

Nitride provides a hard, corrosion-resistant surface that withstands heat cycling and carbon buildup. It's more durable than bare steel and requires less maintenance than blued finishes.

Is this a direct replacement part?

Yes, this mid-length gas tube is designed as a replacement for compatible AR-15 platforms. It will install in place of an existing mid-length tube.
