Rifle Length Gas Tube – Precision & Durability for Your AR Build

When it comes to your AR-15’s gas system, reliability is everything. A rifle length gas tube ensures smooth cycling, reduced recoil, and consistent performance—especially when paired with a matching rifle-length barrel and low-profile gas block.

At Mounts Plus, we carry high-quality AR-15 rifle length gas tubes made from corrosion-resistant stainless steel, built to last through thousands of rounds. Whether you’re upgrading an existing rifle or building from the ground up, this critical component helps maintain the perfect balance between performance and longevity.

Why Choose a Rifle-Length Gas Tube?

A rifle-length gas tube is longer than mid- or carbine-length options, creating a more gradual pressure curve. This results in:

• Smoother cycling with less recoil impulse
• Improved reliability over long shooting sessions
• Lower wear and tear on internal parts
• Ideal compatibility with 20" rifle barrels and precision builds

Our gas tubes are Mil-Spec, precisely machined, and ready for immediate installation. We also offer roll pins and gas blocks if you're doing a full assembly or replacement.

✅ FAQs

Q: Will a rifle-length gas tube fit any AR-15?
A: No. It’s designed specifically for AR-15 rifles with a 20" barrel or longer that use a rifle-length gas system. Always match the tube to your barrel length and gas port placement.

Q: What's the benefit of a rifle-length gas system?
A: It delivers smoother recoil, less wear on parts, and better accuracy—especially over longer shooting sessions or with match ammo.

Q: Do I need a low-profile gas block with this tube?
A: Most builds using a rifle-length gas tube benefit from a low-profile gas block to ensure proper clearance under handguards.

Q: Is stainless steel better for gas tubes?
A: Yes. Stainless steel resists heat and corrosion, making it a great choice for longevity and consistent performance.
