It looks like some of the weapons in Call of Duty: Modern Warfare might need another update as players reporting various bugs with different weapons.
According to some players, some of the weapons in the game have too high of recoil while others have too much range affecting the gameplay of the game. E-Roc, a YouTuber pointed out that the Kilo 141 assault rifle, M-13 assault rifle, MP-5 submachine gun all have a higher recoil when crouching and will be more inaccurate when you crouch.
Polygon also reported that the shotgun, double-barreled 725 will have even more damage to dish out if you choose to add on some extra attachments like the extended barrel, and monolithic suppressor.
No word on when Infinity Ward will be offering an update for these bugs so you might want to take note of it while we wait for them to update the weapons.
