The Faxon Firearms FXSPT55616HBAR13 Sport 16" 5.56 NATO AR-15 HBAR Rifle is built around Faxon’s Duty Series heavy barrel with a black nitride finish and a mid-length gas system for smooth, reliable cycling. Its enhanced forged receivers, free-float Streamline M-LOK handguard, and A2 flash hider create a balanced, optics-ready platform that emphasizes accuracy and durability over long strings of fire.

This Sport model uses a 16" threaded HBAR barrel with 1:8" twist, paired with a forged lower featuring a tensioning screw for a tight upper-to-lower fit. A Mil-Spec trigger and safety, M4-style adjustable stock, and A2-style grip keep controls familiar and straightforward, while the included Magpul Gen M2 10-round magazine gets you range-ready out of the box. Ideal for training, range use, and general-purpose defensive roles, it reflects Faxon’s reputation for thoughtful engineering and consistent manufacturing quality.
