FAXON SPORT 16" 5.56 AR15 HBAR RIFLE

The Faxon Sport 16" 5.56 AR15 HBAR Rifle is a purpose-built, mid-length 5.56 NATO platform for shooters who want balanced handling, exceptional accuracy, and a reliable foundation that performs out of the box. If you’ve ever built or bought a 16" AR and worried about barrel harmonics, heat management during extended sessions, or component consistency, this rifle eliminates the guesswork with a proven, in-house vetted parts stack from Faxon Firearms.

At the core is the Faxon Duty Series HBAR Profile 16" 5.56 NATO barrel (1:8 twist)—manufactured from 4150 CMV steel and black nitride finished (inside and out) for superior durability, corrosion resistance, and sustained precision. The mid-length gas system delivers smoother cycling, reduced recoil impulse, and better long-term reliability compared to carbine-length setups—perfect for range work, training, and defensive applications.

Built by an American manufacturer. Faxon Firearms is a family-owned manufacturer founded in 2012 and headquartered in Greater Cincinnati, Ohio. The Faxon family’s manufacturing and engineering roots date back to 1978—producing mission-critical components for aerospace, defense, and industrial programs. That same process control and machining discipline carries directly into our firearms, barrels, receivers, and critical small parts.

Key Features

  • 16" 5.56 NATO Duty Series HBAR Profile barrel (4150 CMV, black nitride, 1:8 twist)
  • Mid-length gas system for smoother operation and reduced felt recoil
  • Enhanced forged upper receiver for a durable, duty-minded foundation
  • Forged lower receiver with tensioning screw to help tighten receiver fit
  • Faxon Streamline M-LOK handguard

  • Includes Magpul Gen M2 10-round magazine

Use Cases

  • Home & property defense: reliable 5.56 performance with improved accuracy and heat control from the HBAR contour
  • Range & training: heavy barrel reduces stringing during rapid or sustained fire; ideal for classes or high-volume shooting
  • General-purpose / precision builds: balanced weight and mid-length gas make it versatile for optics, lights, and extended sessions

Who it’s for: shooters seeking a 16" 5.56 rifle with enhanced accuracy, durability, and a clear upgrade path (optics, muzzle devices, tuning).
Who it’s not for: buyers prioritizing ultralight weight or maximum maneuverability in tight spaces—this HBAR setup favors stability and precision over minimalism.

FAQs

Why choose the HBAR profile for this 16" 5.56 build?▾

The HBAR (Heavy Barrel) contour provides greater rigidity, reduced barrel whip, and better heat dissipation during extended shooting—resulting in tighter groups and consistent performance. It's ideal for accuracy-focused or high-volume use.

What gas system is used, and why mid-length?▾

Mid-length gas system for smoother, softer cycling with less recoil and wear compared to carbine-length on 16" barrels. It enhances reliability across ammo types and makes the rifle more enjoyable for range days.

What barrel is included, and why does it matter?▾

This build uses the Faxon Duty Series HBAR Profile 16" 5.56 NATO barrel (4150 CMV, black nitride, 1:8 twist). 4150 CMV offers excellent strength and heat tolerance, while nitride provides superior wear and corrosion resistance—perfect for hard-use rifles.

Is this made in the USA?▾

Yes. Faxon Firearms is headquartered in Greater Cincinnati, Ohio, and manufactures core components in-house under controlled processes and inspection standards.

Is this rifle optics-ready?▾

Absolutely—the upper receiver and M-LOK handguard include full-length top Picatinny rail sections for easy mounting of optics, lights, lasers, or irons. Pair it with your preferred red dot, LPVO, or magnified optic.
