The Vepr (Ukrainian: Вепрь, meaning "wild boar", pronounced vai-pr) is an Ukrainian assault rifle that was announced in 2003 as the first indigenous Ukrainian assault rifle, designed by the National Space Agency of Ukraine.
It is one of several bullpup conversions of the conventional AK-74 design, along with the Polish kbk wz. 2005 Jantar and wz. 2002 BIN, the Chinese Norinco Type 86S, the Russian KBP A-91 and OTs-14 Groza, the Finnish Valmet M82 and the South African Vektor CR-21.
Although the Vepr was proclaimed to be a revolutionary upgrade to the AK-74, it is, in reality, an interesting yet fairly simple modification of the basic AK-74 system in a bullpup design, with the following modifications:
- The standard gas-operated, rotating-bolt mechanism is removed from its furniture and a new butt plate is mounted directly on the rear of the receiver.
- A polymer cheek rest is fitted to the receiver cover.
- The trigger and pistol grip are positioned in front of the magazine well.
- The charging handle is removed from the bolt carrier, and a new charging handle arrangement is placed on the left side of the forearm.
