Product Description

The Faxon Firearms Duty Series 16" 5.56 NATO barrel is built for hard-use AR-15/M16 style rifles, combining a SOCOM-profile contour with a mid-length gas system for dependable function and consistent performance. Manufactured from 4150 CMV/Mil-Spec steel and treated with a QPQ black nitride finish inside and out, it delivers enhanced wear and corrosion resistance for easier maintenance and long service life. A precision 11° target crown helps support repeatable accuracy, while standard 1/2-28 muzzle threads and an M4 barrel extension provide broad compatibility with common AR builds.

Product Highlights

  • Duty Series 16" 5.56x45mm NATO AR-15/M16 barrel with SOCOM profile for added stability during sustained fire
  • Mid-length gas system designed to promote smoother cycling and reduced component wear versus shorter gas systems
  • 4150 CMV/Mil-Spec steel construction with QPQ black nitride treatment on bore and exterior for corrosion resistance
  • Button-rifled 1:8 twist rate to stabilize a wide range of common 5.56/.223 bullet weights
  • 11° target crown, 1/2-28 muzzle threads, and M4 barrel extension for build-friendly compatibility
