Overview
The AUP-71 is a 6.5mm, air cooled, gas-operated, magazine-fed assualt rife. The AUP-71 uses a bullpup configuration to shorten the overall length, while still maintaining a long barrel length. Although the AUP-71 is similar in length to a carbine, it is able to achieve accuracy and muzzle velocities similar to a battle rifle. A long stroke gas system was chosen for the design because of its proven reliability in other weapons. Other features, such as the large gas piston and chrome-plated internals also serve to increase the reliability of the rifle.
The upper and lower receivers are constructed of stamped aluminum alloy, which serves to reduce weight and production requirements, although some variants were constructed using stamped steel. The internals of the rifle are made from chrome-plated steel and the grip is made of plastics.

Sights
The AUP-71 has an integrated 3x magnification telescopic sight integrated with the carrying handle. The optic features a combination dot and horseshoe reticle, as well as a range finder. The sight is designed so that aiming at the center of a target will produce a hit within the outer horseshoe at ranges of up to 400 meters. The sight is illuminated by a tritium source so that it can be used in low-light conditions.
Because the optic on the AUP-71 was often one of the most difficult and expensive part to manufacture, many variants manufactured outside of Khyragus were equipped with iron sights on top of the carrying handle see AUP-71E.
