Its magazine holds 30 rounds, and it fires about 700 rounds per minute. It features an optional 40mm GP-95 grenade launcher mounted below the barrel. The A-91 also features a forward case ejection like the Belgian F2000.
"An unusual weapon, even by Russian standards, the A-91 is a bullpup Carbine chambered in the 5.56mm NATO round instead of a Russian caliber. Made from polymers, it features a forward shell ejection system that keeps shells well clear of the shooter’s face upon ejection. The bullpup configuration prevents the A-91 from mounting a foregrip."
