"Developed at the request of the Russian Ministry of Internal Affairs, the Bizon sub-machine gun is primarily intended for counter-terrorist and law enforcement units that usually need fast and accurate fire at close ranges'. Based on the layout of the AKS-74U carbine, the Bizon features a very large magazine capacity."
The Bizon-2B is a 64-round SMG with moderately high damage-per-shot and a slow fire-rate. In fact, it has the second-highest damage-per-shot of all SMGs, behind the H&K UMP45, and it has the slowest fire-rate of all SMGs, slightly behind the H&K UMP45. Unlike the H&K UMP45, the Bizon-2B has an immense magazine size, only behind the Shpagina's 71-round magazine size. The Bizon-2B features the best effective distance (by a small margin) of all SMGs, though its damage fall-off is still very high. The Bizon-2B has relatively low recoil in comparison to SMGs from Set 3 and Set 4, though it still has low accuracy. The Bizon-2B's most outstanding feature is its immense magazine size (and high ammunition reserves), combined with good mobility; however, its reloads are very lengthy.
Overall, the Bizon-2B is a very unique SMG. The combination of a large magazine size and high mobility make the Bizon-2B a powerful flanking weapon. The Bizon-2B is also incredibly good at attaining DoubleKills or better kill combos. However, the slow fire-rate of the Bizon-2B lowers its damage-per-second in comparison to other SMGs.
"Modification kit consisting of a red dot sight kobra and the PBS. Used in silent special operations."
To acquire the W-Task for the Bizon-2B, one must make 30 DoubleKills with this weapon. The Bizon-2B with the W-Task equipped is renamed to the Bizon-2 SPN (SpetsNaz), which will add a red dot sight and a PBS-2 suppressor to the gun. Completing the W-Task also unlocks customization for the Bizon-2B. See Bizon-2B/Customization for more information.
The Bizon-2B can be customized with collimators, optics, silencers, and muzzle-breaks.
The Bizon-2B is the only SMG in the game that has access to a high-power optic, which is the x6 zoom PSO; this optic substantially improves the weapon's accuracy in comparison to reflex and holographic sights. However, by no means is the Bizon-2B capable enough for long-range combat to make the optic distinctively useful.
