Some facts about AN-94 from wiki and other sources :
- The AN-94 was designed at the Izhmash state factories, as a replacement for the AK-74 assault rifle currently in use in the Russian military. Currently, the Russian military has chosen to retain the AK-74M as its standard service rifle and the AN-94 is only being issued to the elite forces of the Russian military, some Russian police forces, and the MVD.
- The initials stand for Avtomat Nikonova (after chief designer Gennadiy Nikonov) Model 1994; The AN-94 was the declared successor to the legendary Kalashnikov series of rifles after the 1980s Soviet Military conducted the extensive Project Abakan advanced assault rifle trials.
- Nikonov AN-94 was commissioned for adoption by the Russian Military, with mass production scheduled at the traditional home of the Kalashnikov, the historic Izhmash state factories.
- The AN-94 is chambered in the same 5.45x39mm M74 cartridge as the AK-74, and it utilizes a rotating bolt to lock the action.
- The stated great advantage of the AN-94 system is its ability to 'postpone' recoil until after the round/s fired have left the weapon. This, it is claimed, enables more 'hits' on target under the most adverse combat conditions.
- Nikonov and the other engineers use the Russian term смещенный импульс свободного затвора (smeshchonnyy impuls svobodnovo zatvora) to describe the rifle's method of operation, meaning "blowback shifted pulse". When the bolt carrier is driven backwards by the force of the gas from the cartridge, a pulley activates a cartridge feeding device. This mechanism allows a much higher rate of fire than would otherwise be possible.
- The AN-94 offers a two-shot burst function at a stated 1800 shots per minute rate of fire. Simply, the Nikonov mechanism 'sneaks' a superfast second round into a one shot recoil cycle. This - In theory, increases the 'hit' probability, as well as penetration of body armor. It was chosen over many other competing firearms in an extensive trial, including the AEK-971 design by a team led by Sergey Koksharov.
- This high rate of fire (1,800 rounds/min) is employed in two-round bursts. These form the first two shots on fully automatic fire, with following rounds fired at 600 rounds/min. This, it is claimed, is highly effective against body armour; the second round supposedly strikes at the same point as the first, enabling the penetration of armour that a standard 5.45 mm system cannot.
- The rear peep sight is an improvement over the standard Kalashnikov notch and post.
- The compound muzzle design is intended to significantly reduce weapon report and muzzle flash.
- The AN-94 design is stated to be vastly more accurate than the AK-74M. And unlike the AK-74M, It can mount a GP-30 grenade launcher and bayonet simultaneously. It can also use newly designed 60-round magazines.
- It is reported that the AN-94 unit manufacture costs are six times greater than the AK-74M. The mechanism of the AN-94 is comparatively complex and reportedly more demanding to maintain than the simple, efficient and rugged AK-74M. Indications are, perhaps, that the Russian Military has found that any advantages of operating the AN-94 are offset by a cumulative cost spiral. Those funds are sorely needed elsewhere in the vast Russian defense budget.
- the ergonomics of the AN-94 is not the best one. The shape of the pistol grip, and the inclined from the vertical plane magazine are way from being comfortable. The rear diopter sight has small apertures, not protected from dirt, and is hard to clean in the battle conditions. It also has sharp edges and can snag in the clothes or make a scratches on the skin when handled roughly. The grenade launcher mount under the barrel is a little weird, since it uses a large "bridge" between the stock and the launcher. The folding butt interferes with the trigger when folded, and the fire selector, which is separated from the safety, is hard to operate, especially when wet. On the other hand, as said above, in the 2-rounds burst it is very accurate and offers a great advantage in the terminal effectiveness over the standard single shot mode. (world.guns.ru)
- Unlike the more common designs, like the Russian Kalashnikov or American M16 rifles and others, the AN-94 internals are not "user friendly", and it took weeks, if not months, to get used to this rifle, its assembly / disassembly and maintenance procedures. It is also more expensive to made and maintain, than the AK-74. From all this it is obvious why this very interesting rifle hardly will see any widespread service, at least with the Russian Army (which at this moment is conscripted by the large, and on a low budget). On the other hand, some elite units can make a good use for major advantages of the AN-94. (as above)
- An interesting fact about the AN-94, setting it apart from almost all other Russian weapons, is that it is not sold to foreign buyers although Venezuela has shown interest in either acquiring the AN-94 or developing an indigenous assault rifle based on the AN-94s recoiling barrel mechanism. Peru also requested a purchase of 580,000 AN-94s to replace the Peruvian army's HK33s but the purchase order was dropped in favor of an indigenous Peruvian rifle, the FAD which also makes use of a recoiling barrel system.
(wiki) AEK-999 Barsuk (Russian : АЕК-999 Барсук) is a Russian machine gun chambered for the 7.62x54mmR round. It's a modernised PKM machine gun. The barrel of AEK-999 is made of the same type of steel used for machine guns in the aviation for greater durability. The odd device at the muzzle (a suppressor) has several roles : increasing accuracy, reducing the noise for the gunner and reducing his acoustic signature (400 to 600 meters, depending on the terrain), eliminating the muzzle flash which makes the gunner hard to pinpoint and ensures accurate fire during the night since the gunner is not blinded by the flash.
