The M4 Super 90 is a fully automatic Shotgun, similar to the SPAS-12, and unlike its pump-action GP variant. It is considered by many to be overpowered because it boasts low recoil, a high rate of fire, and a quick reloading speed.
The M4 Super 90 has a fire rate identical or extremely close to the Saiga 20K, making it the second fastest firing Shotgun next to the AA-12. Unlike the Saiga 20K and AA-12, the M4 Super 90 can fire while reloading. It also has a wider spread than most Shotguns, but it can still kill someone in two shots due to the high damage it deals. The M4 Super 90 has about more damage, a faster fire rate, faster reload, and a larger shell load than the M590 Military.
