Description

Faxon Duty Series SOCOM Profile — 16" Mid-Length 5.56 NATO (1:8 Twist)

Rugged SOCOM contour with smooth mid-length gas timing for duty-grade accuracy and endurance.

The Faxon Duty Series 16" SOCOM Profile 5.56 NATO barrel blends a proven heavy contour with mid-length gas to deliver controllable recoil, excellent heat management, and consistent accuracy over long strings of fire. Manufactured in-house from certified 4150 CMV, finished black nitride inside and out, and verified with air-gauge, MPI, and headspace checks, this barrel is built for real-world reliability.

Key Benefits

  • SOCOM contour: Added material for heat control and stability during rapid or sustained fire.
  • Mid-length gas system: Smoother cycling and reduced component wear versus carbine gas.
  • Duty materials: In-house machined 4150 CMV steel, button-rifled 1:8 twist.
  • Corrosion resistant: Black nitride finish on bore and exterior for longevity and easy maintenance.
  • QC that matters: Stress relieved, air-gauge tested, magnetic particle inspected, and individually headspace-checked.
  • Build friendly: Standard 1/2-28 threads, .750" gas block (1.9" journal), and M4 extension.

Why Choose the SOCOM Profile

The SOCOM profile adds strategic mass for thermal stability and reduced POI shift as the barrel heats up. Paired with mid-length gas, it’s a workhorse choice for patrol carbines, training rifles, and hard-use builds where reliability under heat is non-negotiable.

Installation & Compatibility

  • Standard M4 barrel extension fits AR-15 uppers and bolts.
  • Use a .750" gas block on the 1.9" journal; adjustable blocks recommended for suppressed use.
  • 1/2-28 threads accept brakes, comps, and direct-thread suppressor adapters.
  • Pair with a mid-length gas tube and appropriate buffer system for optimal reliability.

Frequently Asked Questions

How does SOCOM compare to Government profile?
SOCOM retains more mass toward the muzzle for better heat control and stability during rapid fire than standard Government profiles.
Is the barrel chrome-lined?
No — it uses a black nitride treatment inside and out for wear and corrosion resistance.
Can I use a suppressor?
Yes — mid-length gas and the SOCOM contour make an excellent suppressor host. An adjustable gas block helps tune back-pressure.
What ammo weights work best?
The 1:8 twist stabilizes common 55–77 gr 5.56 loads for duty, defense, and match use.

Overview: Duty-Grade 16" Mid-Length SOCOM Barrel

The Faxon Duty Series 16" SOCOM Profile 5.56 NATO barrel is engineered for serious shooters who expect consistent accuracy and long service life from their AR-15. Its heavy contour resists thermal shift and barrel whip, while the mid-length gas system softens recoil and enhances reliability — suppressed or unsuppressed.

Starting with 4150 CMV steel, Faxon button-rifles a versatile 1:8 twist, then stress-relieves, air-gauges, and MPI-inspects every barrel. A black nitride finish protects the bore and exterior from corrosion, and the 11° target crown promotes repeatable accuracy.

For patrol carbines, training rifles, or hard-use duty builds, the 16" SOCOM offers the ruggedness, precision, and QC pedigree that define Faxon’s Duty Series.
