Description

Faxon Integral® Series 16" Light Taper Brake — 9mm (Blowback)

Integrally machined 2-port brake. Legal 16" overall length. Purpose-built for AR-9 blowback systems.

The Faxon Integral® 16" Light Taper 9mm barrel delivers the compact handling of a short barrel with the compliance of a 16" overall length — no pin & weld required. Its integral 2-port muzzle brake is machined as part of the barrel for perfect concentricity, recoil control, and a clean, durable front end.

Optimized for straight blowback AR-9 builds, this barrel features a light taper profile, 4150 CMV steel, and a QPQ nitride finish inside and out for longevity. Feed ramps are compatible with both Glock-pattern and Colt-pattern systems.

Key Benefits

  • Integral 2-port brake: Part of the barrel blank for perfect alignment, improved control, and no timing or shims.
  • 16" legal length: Fully compliant overall length without the hassle of pinning & welding.
  • Blowback-ready: No gas port or block — engineered for AR-9 blowback operation.

  • Durable construction: 4150 CMV steel, button-rifled 1:10 twist, and nitride finish inside & out.

    Faxon Integral® Series 16" Light Taper Brake Blowback 9mm AR-15 Barrel

    Posted by Robert on Aug 24th 2026

    The Faxon Integral Series barrel offers something different from a conventional 9mm AR barrel. The integrated brake, lightweight tapered profile, and 16-inch length create a practical combination for a full-size 9mm AR build. The integrated brake is probably the biggest selling point. It gives the barrel a finished appearance straight out of the box and eliminates the extra step of selecting and installing a separate muzzle device. For a builder looking for a lightweight, reliable, and visually clean 9mm AR-15 setup, the Faxon Integral Series 16" Light Taper Brake Blowback barrel deserves serious consideration.

    Great 16” 9mm barrel option!

    Posted by Mark Bellanger on Jan 6th 2024

    If you are wanting to stick with a 16” barrel and note go the 9mm pistol or SBR route, the integral flash hider and muzzle brake 9mm barrels are awesome options! As usual for Faxon, great fit, finish, and accuracy!

    Fantastic idea

    Posted by Jeff on Aug 15th 2020

    I have both the 5.56 and 9mm 3 port integral barrels and I really hope you expand to other calibers as well. 45 ACP, 10mm, 300 blackout, .308 ect as well as maybe making pistol length versions as well. Can't ask for anything more then these except well... more of these!

    This barrel is fantastic! It shoots sub MOA and everyone I let use the rifle was amazed that they could ring 4" steel disks at 150 yards.
