The Alex Pro Firearms 300 Blackout carbine delivers a compact, versatile platform built for hunters and shooters who need to move fast and shoot hard. This 16-inch 300 Blackout rifle combines a Proof Research carbon fiber barrel with a carbine-length gas system, giving you the ballistics punch of .300 Blackout in a package that handles like a dream in tight cover, vehicles, or from a standing position. Whether you're running subsonic rounds through a suppressor or pushing supersonic loads for extended range, this carbine bridges the gap between precision and practicality.
The 12.5-inch M-Lok rail gives you plenty of real estate to mount optics, lights, and accessories without unnecessary weight. A Magpul CTR adjustable stock lets you dial in the fit to your frame and body armor setup, while the Ergo SureGrip keeps your hand comfortable and stable through extended shooting sessions. The 30-round magazine capacity means you're ready for everything from duty applications to dynamic range sessions.
Alex Pro Firearms builds this rifle to tolerate both suppressed and unsuppressed fire, making it a natural fit for precision hunters who want one gun to do it all. The carbon fiber barrel keeps overall weight down while maintaining the durability you need for hard use in the field.
