The Steyr AUG A3 M2 in .300 AAC Blackout with a 16-inch barrel and green synthetic stock is a semi-automatic bullpup rifle that packs a full-length barrel into a compact, maneuverable platform. Chambered in the versatile .300 BLK, this Austrian-made rifle lets you shoot supersonic and subsonic loads without swapping anything but the magazine. It’s the kind of rifle that makes you rethink what a 16-inch gun can do.

Key Features
- Bullpup Design — WHY IT MATTERS: The action and magazine sit behind the trigger, giving you a 16-inch barrel in a rifle that’s over six inches shorter than a traditional AR. That means easier handling in tight spaces, from truck cabs to shooting lanes.
- .300 AAC Blackout Chambering — WHY IT MATTERS: You can run supersonic rounds for flat-shooting out to 400 yards, or swap to subsonic loads for whisper-quiet suppressed shooting. No buffer tube changes, no gas system tweaks—just load and go.
- Ambidextrous Controls — WHY IT MATTERS: The factory setup is right-hand, but the AUG A3 M2 can be converted for left-hand shooters with available parts. The charging handle is non-reciprocating and can be swapped to either side.
- Integrated Optic Rail — WHY IT MATTERS: The top rail runs the full length of the receiver, so you can mount any red dot, LPVO, or night vision without special adapters. The factory iron sights are also included for backup.
- Quick-Change Barrel System — WHY IT MATTERS: If you ever want to swap calibers or replace the barrel, it takes about 30 seconds with no tools. That’s a big deal for shooters who like to experiment with different loads.
Who It’s For
This rifle is built for recreational shooters who want something different from the standard AR-15. If you’re a first-time buyer looking for a compact, accurate, and easy-to-maintain platform, the AUG A3 M2 delivers. It’s also a natural fit for home defense or truck gun duty—short enough to maneuver, but with a full 16-inch barrel for velocity. The .300 BLK chambering makes it a favorite among suppressors owners who want to go quiet without losing reliability.
Pros and Cons
- Pro: Compact package with full-length barrel. No other 16-inch rifle fits in a 28-inch overall length.
- Pro: Legendary Steyr reliability. The AUG has been in service since the 1970s for a reason.
- Pro: Sub-MOA accuracy with quality .300 BLK ammunition out of the box.
- Con: The trigger is not as crisp as aftermarket AR triggers. It’s a two-stage design with a bit of creep, but it’s consistent and predictable.

FAQ
Can I use standard AR-15 magazines with this rifle?
Yes, the AUG A3 M2 in .300 BLK accepts standard AR-15 pattern magazines, including the included 30-round magazine. Just make sure they’re .300 BLK specific or marked for 5.56—the rounds are similar but not interchangeable in all cases.
Is the barrel threaded for a suppressor?
Yes, the 16-inch barrel comes with a standard 5/8×24 thread pattern, which is common for .30 caliber suppressors. You’ll need a direct thread or QD mount compatible with that thread.
Can I shoot both supersonic and subsonic .300 BLK without modifications?
Absolutely. The gas system is designed to cycle both types reliably. For subsonic loads, you may want a suppressor to keep the action running smoothly, but it’s not required.
Is the stock adjustable for length of pull?
No, the AUG A3 M2 has a fixed length of pull. However, the bullpup design naturally places the grip farther forward, so most shooters find it comfortable. Aftermarket cheek risers and buttpad spacers are available if needed.
