The Steyr AUG A3 Multi-Purpose is a versatile bullpup airsoft rifle from ASG. Bullpup means that the action of the rifle is located behind the trigger. This allows the rifle to have a longer barrel in a more compact gun. This makes the gun more accurate than a standard rifle of the same length and also more maneuverable than standard rifles of with the same length barrel. This AUG has a total of 9 rails, 7 of which are removable, for easily adding optics and other accessories anywhere you may need them. The stock, grip and magazine of the weapon are made of impact resistant, high quality ABS plastic. The barrel extension/mock-suppressor is removable and replaceable with other aftermarket barrel accessories. The magazine itself holds 330 rounds. The hop up is adjustable for increased accuracy. The sling attachment points are made of metal, they are located at the front and rear of the weapon. If you're looking for a high quality, accurate Proline AEG with a unique look and feel, this is a great choice!
