Alex Pro Firearms 5.56 Nato Fury 16 Liberty Fx Mlok

The Alex Pro Firearms 5.56 NATO Fury 16 is a purpose-built modern sporting rifle built on a platform that puts accuracy and reliability within reach. This semi-auto rifle pairs a 16-inch 4150CM nitride-coated barrel with a mid-length gas system and a user-adjustable gas block, giving you the flexibility to fine-tune performance whether you're running suppressed, pushing velocity, or dialing in precision on the range. The 1:7 twist rate handles the full spectrum of 5.56 ammunition, from lighter varmint loads to heavier match and hunting rounds.

Built around a forged receiver and dressed in a Liberty FX Cerakote finish, this rifle splits the difference between duty-grade durability and a distinctive look. The handguard is APF's 15-inch M-LOK design, giving you plenty of real estate for mounting lights, lasers, or other accessories without unnecessary bulk. Inside the trigger guard sits APF's proprietary 4.5 lb. drop-in trigger—crisp enough for precision but friendly for duty use—while the diamond-honed nitride bolt carrier group is built to last. Controls are all Magpul: MOE pistol grip and MOE PR stock keep you comfortable and in control whether you're working from a bench or the field.

This is a no-frills, go-to-work rifle for shooters who want semi-automatic 5.56 capability without unnecessary complications. Whether you're building a precision rifle, setting up a home-defense platform, or just want a dependable plinker with quality internals, the Fury 16 delivers the essentials with attention to detail.
