The AUP-71, officially designated the Univerzalna Avtomatska Puška 1971 (Khyragusian: Универзална Автоматска Пушка 1971, 'Universal Automatic Rifle 1971') is a gas operated, 6.5x45mm assault rifle developed in Khyragus by the Khyragusian Military Industries Corporation in the 1960s. In 1971 the AUP-71 was officially adopted by the Khyragusian Armed Forces. The AUP-71T2M a modernized variant without integrated optics and a picatinny rail was introduced and adopted into service in 1995.
Since its introduction, the AUP-71 has been widely used by both professional militaries and insurgency groups. Because of it's low manufacture cost, simple design, and reliability the AUP was manufactured in several countries and widely proliferated.
History
Concept
In the early 1960s, the Khyragusian Armed Forces lacked a designated service rifle and were primarily organized as a militia style force, using a mix of different rifles with varying calibers. This was noted by senior Khyragusian commanders as a key weakness, which would be exploited in the event of a major conflict. To address this, the Khyragusian military initiated the New Infantry Program, which was tasked with creating modern and standardized equipment that would integrate into the broader strategic changes being made to the military.
The Khyragusian military sought a selective fire rifle that would be cheap to mass produce, easy to use, and comparable to the rifles used by contemporary militaries during this time. Military planners desired a rifle compact enough to be easily used by the newly developing mechanized infantry forces. Initially, the military sought out existing rifle designs in use by other militaries, however, they were unable to find a weapon that satisfied all of their requirements. International political difficulties during this time posed further problems. As a temporary solution, the Khyragusian Army adopted the AP-57 for units operating outside of Khyragusian borders. Following this decision, work began immediately on a new, domestic rifle which could address the military's requirements.
Development
Following the international developments in intermediate caliber rifles, the 5.8x45mm KVI round was developed for use in the new standardized rifle design. The new round showed favorable ballistics, retaining higher energy than both the 5.56x45mm NATO and the 7.62x39mm rounds at extended ranges, while also providing low recoil.
In 1966, the Khyragusian military began a design competition to develop a rifle for the new 6.5mm round. In 1968, Kuslev Design Bureau's rifle, then known as the EUP-4, was chosen as the winner of the competition.

Design
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.

Operating Mechanism
Barrel
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.
