The AN-94 (Abakan) is an advanced assault rifle of Russian origin. The initials stand for Avtomat Nikonova model of 1994, after its chief designer Gennadiy Nikonov.
The stated great advantage of the AN-94 system is its ability to delay the recoil force until the fired round/s have left the barrel. This, it is claimed, enables more 'hits' on target under the most adverse combat conditions.
The AN-94 offers a unique two-shot burst function at a stated 1800 rounds per minute rate of fire. The Nikonov mechanism fires the second shot in the burst quickly enough to allow it to escape before the recoil of the first shot is felt, thus potentially allowing the two shots to hit extremely close together, for example to aid in piercing body armor.
The most conspicuous identifying feature of the AN-94 is its magazine which is canted several degrees to the right of center (when viewed from a firing position). This design feature is necessary to accommodate the unique ammunition feed mechanism. 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. (wikipedia)
