The Alexander Arms Standard .300 AAC 16" tactical rifle delivers a purpose-built platform for hunters and shooters who want effective suppressed-fire capability in a lightweight, handy package. Chambered in .300 AAC Blackout—a cartridge purpose-designed for subsonic ammunition and sound suppressors—this semi-automatic rifle gives you the flexibility to run supersonic loads for hunting or subsonic rounds for stealth operations. At just 6.25 pounds, it's nimble enough for tactical drills or predator control without wearing you out in the field.
Built on a direct impingement operating system, the Alexander Arms Standard features a 16-inch barrel threaded 5/8-24 RH (right-hand) with a thread protector included, so you're ready to add a suppressor when you're ready. The 1:8 twist rate stabilizes a wide range of .300 Blackout projectiles, whether you're handloading or buying factory ammunition. The rifle ships with one 30-round magazine (subject to local restrictions) and includes an Alexander Arms soft carry bag for transport and storage.
The ergonomic setup keeps things mil-spec and familiar: standard AR trigger, A2 grip, M4 stock, and Alexander Arms-branded hand guards that provide plenty of rail real estate for optics, lights, or laser systems. The black anodized finish resists corrosion during extended range sessions or field use. Whether you're setting up a subsonic hunting rig, running drills at the range, or testing suppressor configurations, the Alexander Arms Standard .300 AAC offers reliability and modularity without unnecessary frills.
