Steyr Mannlicher AUG A3 M2 NATO 5.56 NATO 16.3700 in 30rd
About this product
The Steyr Mannlicher AUG A3 M2 NATO 5.56 NATO 16.3700 in 30rd brings the legendary bullpup design into a modern sporting configuration that’s perfect for the range, practical shooting, or home defense. As your local gun shop owner, I’ve seen shooters fall in love with this rifle because it keeps the barrel long while the overall length stays short — that’s the beauty of a bullpup. Chambered in .223 REM/5.56 NATO, it ships with a 30-round detachable magazine and a synthetic bullpup stock for space-efficient handling. The controls are intuitive for right-handed shooters, and the compact layout makes it easy to maneuver in tight spaces. Whether you’re a new shooter or a seasoned competitor, this AUG delivers reliability and accuracy right out of the box.

Key Features
- Compact Bullpup Design — The 16.37-inch barrel fits into an overall length of just 28.9 inches, making it handier than most traditional rifles without sacrificing velocity or accuracy. Why it matters: You get full rifle ballistics in a package that’s easy to carry, store, and shoulder quickly.
- NATO STANAG Compatibility — This A3 M2 model accepts standard AR-15 pattern magazines, so you can use the same mags across your collection. Why it matters: No need to hunt for proprietary mags — grab your existing 30-rounders and go.
- Quick-Detach Barrel System — The barrel can be removed in seconds for cleaning or swapping without tools. Why it matters: You can maintain your rifle easily and even pack it in a smaller case for transport.
- Integrated Optical Sight — The factory-installed 1.5x optic is zeroed at the factory and stays locked in place. Why it matters: You’re ready to shoot as soon as you open the box — no mounting or bore-sighting needed.
- Ambidextrous Ejection Port — The bolt can be swapped to eject from the left side for left-handed shooters. Why it matters: Lefties don’t get brass in the face, and right-handed shooters can still use it comfortably.
Who It’s For
This rifle is built for anyone who wants a compact, reliable semi-auto that doesn’t compromise on barrel length. It’s ideal for home defense because you can maneuver it in hallways and doorways. If you’re a practical shooter or competitor, the short overall length and fast handling give you an edge in tight courses of fire. New gun owners will appreciate the simple controls and easy maintenance — the AUG is famously reliable and forgiving. And if you’re a collector, this is a modern classic from a brand with over 50 years of bullpup innovation.
Pros & Cons
- Pro: Extremely compact — 28.9 inches overall with a 16.37-inch barrel means you get rifle velocities without the length.
- Pro: NATO magazine compatibility lets you use common AR mags, saving money and hassle.
- Con: The trigger pull is heavier and less crisp than a traditional AR-15’s — it’s a bullpup trade-off. According to Steyr Mannlicher specs, the trigger is designed for durability and reliability over match-grade feel.
- Pro: Built like a tank — the polymer stock and steel barrel are tough enough for hard use.
- Con: Left-handed shooters need to swap the bolt and ejection port, which takes a few minutes but is doable at home.
