A-91
The A-91 is a Russian bullpup assault rifle developed by the KBP Instrument Design Bureau during the 1990s. It is an evolution of the earlier 9A-91 carbine, primarily designed to be compact, reliable, and versatile in urban combat scenarios. The rifle is notable for its integrated 40mm grenade launcher and the use of a bullpup configuration, which positions the magazine behind the trigger, allowing for a more compact design without sacrificing barrel length.
Design and Features
The A-91 uses a gas-operated system with a rotating bolt, similar to the AK-47 and other Kalashnikov designs. However, unlike most Russian rifles, it adopts a bullpup layout, which reduces the overall length while maintaining a full-length barrel, improving handling in confined spaces.The rifle can be chambered in multiple calibers,
including the standard Russian 5.45×39mm and 7.62×39mm rounds, as well as the NATO- standard 5.56×45mm NATO cartridge. Its rate of fire is approximately 600 rounds per minute, with a muzzle velocity of 880 m/s.
One of the most notable features of the A-91 is its integrated under-barrel grenade launcher, designed to fire standard 40mm grenades such as the VOG-25. The launcher has a range of up to 400 meters. The rifle also has a spent-case ejection system that ejects casings forward, preventing interference with the user's face or arms when firing from the left shoulder.
