Faxon Duty Series 16 inch Gunner 350 Legend barreled upper

Faxon Duty Series 16" Gunner 350 Legend Barreled Upper

Built for straight-wall hunting performance in an AR-15 footprint—lightweight handling, duty-grade durability, and suppressor-ready threading from an American manufacturer in Greater Cincinnati, Ohio.

350 Legend • Hunting/Field 16" Gunner Profile Duty Series 4150 CMV Salt Bath Nitride Suppressor Ready Made in Ohio, USA

What it is

The Faxon Duty Series 16" Gunner 350 Legend Barreled Upper is a purpose-built, suppressor-capable upper designed for hunters and practical shooters running the 350 Legend in AR-15 platforms. The Gunner contour keeps weight down where it matters for carry and transitions, while preserving strength at the chamber for real-world durability.

At the core is a Faxon Duty Series 4150 CMV barrel manufactured in-house using controlled processes developed through decades of advanced machining heritage. Duty Series barrels are salt-bath nitrided for wear/corrosion resistance and built with the reliability-first mindset buyers expect from a manufacturer—not a reseller.

This upper is ideal for whitetail and hog hunting in straight-wall states, and for shooters who want an efficient, low-recoil hunting cartridge that still feeds and runs like an AR should. If you’re building for the field, this is the “grab-and-go” configuration that closes the decision gap.

 

Who it’s for / not for

  • Best for: Straight-wall hunting setups, truck/field rifles, practical range use, lightweight builds.
  • Good match: Standard AR-15 lowers, optics-ready hunting builds, suppressor-ready muzzle device ecosystems.
  • Not ideal for: Buyers seeking a complete rifle (this is an upper), or those needing a different barrel length/profile for specialized balance preferences.

Key features

  • 16" Gunner Profile for faster handling without unnecessary front weight
  • Duty Series 4150 CMV barrel construction (duty-grade material choice)
  • Salt Bath Nitride protection for long service life and easier maintenance
  • Carbine-length gas system for proven cycling characteristics
  • Suppressor-ready threaded muzzle + standard muzzle device compatibility
  • Made in the USA by Faxon Firearms in Greater Cincinnati, Ohio
