Steyr AUG A3 M1 NATO 5.56 Bullpup Rifle with 16" Cold Hammer Forged Barrel & Flat-Top Rail
The Steyr AUG A3 M1 NATO pairs the classic Austrian bullpup design with a U.S.-made receiver that accepts standard AR-15 magazines. Its 16" chrome-lined, cold hammer forged barrel can be swapped in seconds, while the flat-top rail lets you mount optics at the height you prefer. A non-reciprocating charging handle with forward-assist capability, 3-position gas regulator, and ambidextrous safety round out a feature set geared for practical versatility.

What’s Included
- Steyr AUG A3 M1 NATO Flat-Top rifle
- One 30-round metal USGI-pattern AR-15/STANAG magazine
The NATO stock configuration positions the magazine well to accept widely available AR-15 magazines, and its NATO-style release is familiar to most shooters. The bullpup layout keeps the overall length to roughly 28" while still providing a full 16" barrel for optimal velocity.
The quick-change barrel system allows you to detach the chrome-lined barrel by flipping a single lever—useful for transport, maintenance, or caliber conversions. A bird-cage flash hider comes installed.
A 3-position gas regulator lets you fine-tune the short-stroke piston system for standard, adverse, or suppressor settings. Combined with the non-reciprocating charging handle and forward assist, the design supports reliable operation in varied conditions.
Controls are ambidextrous: a push-through safety blocks the trigger, and sling loops on the reinforced polymer stock aid left- or right-hand carry. The integral folding vertical fore-grip provides added control without increasing overall length.
