Battlefield 3 A-91
Battlefield 3 A-91
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.
