Availability: In Stock
The Alex Pro Firearms Carbine 2.0 is a 5.56 NATO rifle built on a modern, modular platform that balances versatility with reliable performance. With a 16-inch barrel and mid-length gas system, this carbine is equally at home in the field, at the range, or as a practical home-defense or duty rifle. The M-LOK handguard gives you room to mount lights, lasers, or other tactical gear without the cost or weight of a rail-heavy setup, while the 30-round capacity keeps you in the fight longer between reloads.
Alex Pro Firearms has equipped this carbine with proven components throughout. The barrel is 4150 steel with a hard Nitride coating for corrosion resistance and durability, and the bolt carrier group is also Nitride-treated for longevity. Billet upper and lower receivers provide a tight, precise fit, and the included Magpul MOE SL adjustable stock and MOE grip are field-tested controls that work well in any condition. The .750 mid-length gas tube is a sweet spot for cycling—not overgassed, not undergassed—and works with standard 5.56 ammunition.
This is a no-nonsense, modular AR platform carbine that rewards you with solid ergonomics, room to customize, and the kind of reliability you expect when your life or mission depends on it. Whether you're running it bone stock or adding your own optics and accessories, the Carbine 2.0 is a solid foundation that won't let you down.
