FAXON DUTY SERIES SOCOM PROFILE 16" MID-LENGTH 5.56 NATO AR15 BARREL
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.
Specifications
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.

Awesome barrel
Accurate, light, and slick. Top notch machine work and the QPQ coating is extremely well done. Slides into an upper like butter. Chambers and functions with everything I have thrown at it without a hiccup, heavy or light, hot imi ss109 to wolf 223. It's dropping M193 within spec at 100. It's not a match grade barrel but it's not far off with match ammo. It's way more than it should be for the price and duty capable all day long. I'm extremely satisfied.

16" govt/socom 556 barrel

great barrel
This barrel is a good quality barrel. I originally purchased this in July, but later had to return mine due to it not having correct feed ramps. Faxon payed for return shipping and got me a brand new barrel fast. I did not put this in the review to deter anyone from buying this barrel. I just noted it since it was what happend. Every manufacturer has an occasional issue that does not get caught. Once I installed and zeroed the barrel I was happy with its performance. I havent got a chance to shoot past 50 yards, but I expect this barrel is easily a sub moa barrel with the right ammo. I would not hesitate to purchase again

Sub MOA
This is a spectacular barrel irrespective of price. After a 100 round break-in period in accordance with Faxon procedures, the rifle easily gave me sub-MOA results with decent handloads (68gr Hornady BTHP over 24gr of Varget, My next build will definitely include a Faxon barrel!

great deal!
I haven't got to shoot many rounds through this barrel yet but while trying to sight in my scope I was getting many clover leaf holes at 100 yards with cheap perfecta ammo! I was very impressed with the quality of this barrel and if I was to build another upper wouldn't hesitate to buy from Faxon again! So happy I went with this barrel and anyone else would be too!
