About this product

A solid .300 Blackout AR for hunting, short-range work, or putting another reliable rifle in the safe. Straightforward build with a 16-inch barrel, M-LOK rail, and a 30-round magazine. Good option if you’re building a dedicated .300 Blackout without breaking the bank.

You’re looking at a .300 Blackout AR-15 built to get the job done. This American Tactical Imports Omni Maxx Hybrid is a practical choice for hunters taking advantage of Montana’s generous seasons, for folks wanting a quieter short-range option, or just adding another reliable rifle to the collection. It’s a complete rifle, not an upper or lower alone, and comes with the magazine.

What you get with the ATI Omni Maxx Hybrid in .300 Blackout

This isn’t a fancy rifle, and that’s okay. It’s a solid performer built around a 16-inch phosphate barrel with a 1:8 twist rate. That twist rate stabilizes a wide range of bullet weights, making it versatile for different .300 Blackout loads. The barrel is paired with a low-profile gas block.

  • Chambering: .300 AAC Blackout (also sometimes called .300 Blackout)
  • Barrel Length: 16 inches
  • Barrel Twist: 1:8
  • Handguard: 10-inch M-LOK aluminum rail. Gives you plenty of space for mounting accessories like lights, grips, or a bipod, and the M-LOK system is widely compatible.
  • Upper & Lower Receivers: Polymer. Keeps the weight down and helps with cost without sacrificing functionality.
  • Stock: M4 six-position adjustable stock. Lets you adjust the length of pull for a comfortable and customized fit.
  • Magazine: Includes one 30-round polymer American Tactical magazine.
  • Optics Ready: The upper receiver is designed to accept standard optics.

Why a .300 Blackout?

The .300 Blackout cartridge has a lot going for it. It offers good performance at shorter ranges, and the subsonic loads with heavier bullets are popular for areas where noise is a concern. It’s been adopted by hunters and those wanting a compact and effective option for home defense. In Montana, the .300 Blackout is a legitimate choice for deer and other big game within its effective range, and the lighter recoil is a bonus for some shooters.

Good for:

  • Hunting: Deer, hog, and other medium game at shorter ranges.
  • Range Use: A different experience from 5.56, and the .300 Blackout is fun to shoot.
  • Home Defense: A capable and effective option.
  • Building a dedicated .300 Blackout rifle: This is a complete rifle, so you can start using it right away.

This ATI Omni Maxx Hybrid delivers a functional .300 Blackout platform without a lot of extras you may not need. It’s a good, honest rifle that’s ready to go to work.
