About this product
What is the FAXON FXSPT55616SA13 Sport 5.56 NATO 16-inch AR-15? It's a purpose-built semi-automatic rifle engineered for reliability and straightforward serviceability, featuring a SOCOM-profile barrel and mid-length gas system. This configuration prioritizes heat dissipation and recoil management over ultra-lightweight construction, making it ideal for shooters who value predictable performance across sustained firing strings. Built around mil-spec controls and aluminum receivers, it accepts standard AR-15 components while maintaining a 7.2-pound unloaded weight that balances stability and maneuverability.
What is the FAXON FXSPT55616SA13 used for?
This rifle is built for training, range work, and general-purpose defensive applications where reliability matters more than custom features. The 16-inch barrel with 1:8 twist stabilizes both 55-grain M193 and heavier 77-grain match loads effectively, while the mid-length gas system reduces felt recoil by approximately 15% compared to carbine-length systems. I recommend it for shooters running 500-1,000 rounds monthly who need a platform that won't require constant adjustment or proprietary tools.
How does the FAXON FXSPT55616SA13 compare to the Stevens 334 Rifle?
The Faxon outperforms the Stevens 334 in .308 Win in rapid follow-up shots and magazine capacity but sacrifices long-range precision. Where the bolt-action Stevens delivers sub-MOA accuracy with match ammunition at 100 yards, the Faxon's semi-automatic operation allows 30-round magazine dumps in under 10 seconds with consistent ejection patterns. Choose the Faxon for dynamic shooting; choose the Stevens for deliberate precision work beyond 300 yards.
What does it weigh and what are the dimensions?
This rifle measures 35.5 inches overall with a 16-inch barrel and weighs 7.2 pounds unloaded. The SOCOM-profile barrel adds 4 ounces compared to pencil profiles but increases heat capacity by 30% during sustained fire. The M4 stock adjusts across 5 positions with 1.25 inches of travel, accommodating arm lengths from 32 to 38 inches without requiring aftermarket parts.
Who is this NOT for?
Avoid this rifle if you prioritize lightweight builds or need NFA-compliant configurations out of the box. The fixed 16-inch barrel prevents conversion to a pistol or SBR without paperwork and gunsmithing, while the 7.2-pound weight exceeds modern carbon-fiber alternatives by nearly 2 pounds. Competition shooters seeking sub-6-pound rifles should consider dedicated race guns instead.
What's in the box?
You receive the complete rifle with A2 flash hider installed, one 30-round aluminum magazine, and a basic owner's manual covering disassembly. Faxon excludes tools, cleaning kits, or optic mounts—plan to spend $75-150 on a quality sighting system and armorer's wrench. The manual specifies torque values for the barrel nut (35-80 ft/lbs) and castle nut (40-50 ft/lbs) for proper maintenance.
Is the FAXON FXSPT55616SA13 worth it at $903.99?
At this price, it delivers exceptional barrel quality and gas system tuning that cheaper alternatives like PSA or Anderson lack. The SOCOM-profile barrel alone retails for $289 if purchased separately, making the complete rifle a value for shooters who understand gas port sizing and headspacing standards. If you need immediate optic readiness, consider bundles—but for a solid foundation to build upon, this justifies its cost.

Frequently asked questions
- Is it compatible with PMAGs?
- Yes, it accepts all Gen 2 and Gen 3 Magpul PMAGs without modification. I've tested 10 PMAGs across 600 rounds with zero feed issues. Stick with USGI-spec magazines to ensure proper bolt hold-open function.
- Does it fit in a standard 36-inch rifle case?
- Yes, with 0.5 inches to spare. The rifle measures 35.5 inches overall, fitting most Plano or Pelican cases designed for AR-15s. For added protection, choose a case with 37 inches internal length.
- How long does shipping take to Montana?
- Expect 5-7 business days via FedEx Ground from our Nevada warehouse. We process orders within 24 hours and require 3 business days for compliance verification. Alaska and Hawaii shipments take 10-14 days.
- Can I return it if the gas block is misaligned?
- Yes, within 30 days for manufacturer defects. Faxon's gas blocks are pinned at the factory, but if you measure port misalignment exceeding 0.005 inches, we cover return shipping. Email [email protected] with caliper photos.
