ATI ATIGAX30013ML Alpha Maxx 300 Blackout 30+1 16" Black Threaded Barrel, Black Picatinny Rail Polymer Receiver, 13" Polymer Handguard, ATI MM4 Black Synthetic Stock, Black Polymer Grip, Right Hand

The ATI Alpha Maxx 300 Blackout is a modern, modular tactical rifle built on a polymer receiver platform and designed for shooters who want the flexibility to run suppressed ammunition, subsonic loads, or standard velocity rounds. At 16 inches, the threaded barrel gives you the option to attach a suppressor for hearing protection and reduced recoil signature—a huge practical advantage whether you're hunting hogs, running drills at the range, or setting up a truck gun for emergency use. The 30+1 magazine capacity puts you in the fight with plenty of reserve ammunition.

What makes the Alpha Maxx stand out is its balanced approach to modularity without unnecessary complexity. The 13-inch polymer handguard features M-Lok slots, so you can mount lights, lasers, grips, and rail sections exactly where you need them. The Picatinny rail on the receiver gives you a solid upper optics mount. The synthetic MM4 stock and polymer grip keep weight reasonable while maintaining a business-like appearance. All-polymer construction means less weight than a traditional carbine, without sacrificing the durability most shooters expect from a .300 Blackout platform.

The .300 Blackout cartridge itself deserves mention: it's a proven, versatile intermediate round that runs efficiently in this 1:8 twist barrel. Whether you're running it suppressed for stealth or unsuppressed for hunting applications, the 300 Blackout delivers energy and reliability with a proven track record in the field and on the range. This is a rifle for the practical shooter who wants to build it their way.
