AEK-971

The AEK-971 was developed to participate in a competition announced by the Ministry of Defense of the USSR, during which preference was given to the AN-94. The prototype of the AEK-971 differs from the production model, as many innovations were perceived as unnecessary by the Ministry of Defence, which led to a simplification of the prototype. Initially, the prototype featured a 2-round burst mode, which was later changed to a 3-round burst mode in the production model. The AEK-971 is approximately lighter than the AN-94, simpler in design and cheaper to manufacture. The AN-94, which was officially adopted by the Russian army, has a slight accuracy edge over the AEK-971 in its 2-round-burst mode. However, in full automatic mode or during longer bursts (3–10 rounds per burst), the AEK-971 is more accurate. Although it lost the initial production contract to the AN-94 as a result of the Project Abakan assault rifle selection trials held in Russia from 1980 to 1994, the Russian Army still began field trials for the AEK-971. The AEK-971 has been combat proven in Chechnya tested by naval infantry and interior forces, and prepared for mass production. Only a few small batches of the AEK-971 have been produced so far and adopted for service with units of the Ministry of Justice of the Russian Federation. Ratnik trials On 23 December 2014, the Russian Army announced a variant based on the AEK-971, designated as the 6P67 KORD (official GRAU designation 6P67), along with the AK-12 had both passed (Ratnik) state trials and would be accepted into service and set for evaluation with operational units in early 2015. Both systems were recommended for initial batch production and issue for trials in the field. It is possible that in the end both rifles will be adopted by Russian military and other agencies, with the AEK series being oriented towards Special Operations Forces (Spetsnaz) and AK-12 towards infantry and other units. It was expected that both rifles would be tested operationally with the Russian military by March 2015. In January 2018 it was announced that the 6P67 KORD has been adopted in 5.45×39mm and 7.62×39mm chamberings by the Russian military. ==Design details==

The AEK-971 is based on previous AK-type rifles in internal design and layout, but features a Balanced Automatics Recoil System (BARS) that enhances the traditional Kalashnikov long stroke gas piston operating system by reducing the negative effects of recoil. Balanced recoil systems were previously applied in the AO-38 and AL-7 experimental assault rifles and in the AK-107, AK-108 and AK-109. BARS works by shifting mass toward the muzzle of the rifle as the bolt and bolt carrier recoil rearward by way of a counter-weight that negates the impulse of the gas piston and bolt carrier, resulting in more controllable automatic fire. For the AEK-971 automatic firing accuracy is improved by 15-20% in comparison with the AK-74M. The AEK-971's iron sights features an adjustable notched rear tangent rear sight calibrated in increments from and a hooded front post. Each AEK assault rifle is fitted with a Warsaw Pact side-rail bracket for mounting optics. The travel distance of the reciprocating parts of the AEK-971 is less than compared to the non-balanced recoil AK-pattern designs, thus increasing its cyclic rate of fire significantly. The original cyclic rate of fire of the prototype model was 1,500 rounds per minute and was later decreased to 900 rounds per minute for the production model. The AEK-971 is fed through AK-74, RPK-74 pattern 5.45×39mm 30-round or larger box magazines. ==Variants==

The AEK-971 has also been developed in 5.56×45mm NATO (AEK-972) and 7.62×39mm (AEK-973). The different variants are most easily recognised by their respective magazine curvatures. An improved variant of the AEK-971 has also been developed, designated as the AEK-973S. Heavily improved variants of the AEK-971 and AEK-973 were later developed, designated as the 6P67 KORD and 6P68 KORD respectively, which are intended for use by the Russian special operations forces (Spetsnaz). It has numerous internal and external improvements over earlier AEK-971 models. The changes includes iron sights that consist of a rotary rear drum aperture and a hooded front post creating a significantly longer sight line, an ambidextrous fire mode selectors/safety levers, a 2-round burst feature, retractable and adjustable shoulder stock. Also the Warsaw Pact side-rail bracket is omitted and replaced by a Picatinny rail on a redesigned receiver top for mounting auxiliary equipment, such as optical red dot sights. A variant equipped with a suppressor is known as the 6P67-1 KORD. 6P68 KORD The 6P68 KORD, also known as the A-762 during its developmental stage (official GRAU designation 6P68), is based on the AEK-973, evidently of similar design to the 6P67 KORD, but chambered in 7.62×39mm cartridge. A variant equipped with a suppressor is also available, known as the 6P68-1 KORD. ==Users==

• : AEK-971s were produced in small batches and delivered to units of the MVD Internal Troops (paramilitary gendarmerie-like forces) and other law enforcement agencies of Russia. Serial production then began in April 2020. ==See also==
