FAXON DUTY SERIES 16" SOCOM 5.56 BARRELED UPPER
Built for demanding duty and tactical use — heavy SOCOM contour for outstanding heat control and sustained accuracy, mid-length gas system for smooth reliable cycling, 1:8 twist stabilizing 55–77 grain projectiles, and finished with a classic A2 flash hider — all precision-manufactured by Faxon Firearms in Greater Cincinnati, Ohio.
5.56 NATO • Duty/Tactical 16" SOCOM Profile Duty Series 4150 CMV Black Nitride QPQ 1:8 Twist Mid-Length Gas Made in Ohio, USA
What it is
The Faxon Duty Series 16" SOCOM 5.56 Barreled Upper delivers rugged, no-nonsense performance built for high-round-count training, defensive use, and hard-duty applications. The heavy SOCOM profile places mass forward to manage heat, reduce mirage, and maintain tight groups even during extended strings of fire — exactly what law enforcement, competitive shooters, and serious home-defense builders demand.
Core component is Faxon’s in-house button-rifled Duty Series 4150 CrMoV barrel with 1:8 twist, magnetic particle inspected, stress-relieved, and protected by a durable black nitride (QPQ) finish. Paired with a smooth mid-length gas system and completed with Faxon’s premium Streamline 15" M-LOK handguard, fixed low-profile gas block, and stainless mid-length gas tube. Ships with a standard A2 flash hider (1/2×28) for effective flash reduction and broad muzzle-device upgrade compatibility.
Reliable, accurate, and ready for real-world abuse — the Duty Series SOCOM upper you can trust when it counts.

- Best for: Hard-use tactical rifles, high-volume training, duty & LE builds, defensive setups that prioritize heat management and long-term durability.

FAQs
Will this upper work on any standard AR-15 lower?▾
Yes — completely compatible with any mil-spec AR-15 lower receiver.
Is the barrel suppressor-ready?▾
The 1/2×28 threaded A2 flash hider allows attachment of direct-thread suppressors. For quick-detach suppressor systems, you may want to upgrade to a compatible muzzle device (see Faxon’s MuzzLok® or other QD options).
Where is this upper manufactured?▾
100% made in the USA — barrel, machining, assembly, and final QC all performed by Faxon Firearms in Greater Cincinnati, Ohio.
What does the SOCOM profile do better than a government or lightweight barrel?▾
The heavier contour dramatically improves heat management and reduces mirage, helping maintain accuracy and point of impact during rapid or prolonged fire — ideal for duty, training, and defensive use.
Does this upper include BCG and charging handle?▾
No — this is a complete barreled upper only. You will need to add a bolt carrier group and charging handle (see related shopping links above).
