“Bullet speed” is how fast the bullet travels after pressing the fire button. LC-10 with the task force barrel equipped is supposed to have good bullet speed (as the task force barrel increases the bullet speed by 75%), but that’s not the case, it’s bugged meaning its bullet speed is very, very slow and it’s bugged for so long.
Mac-10 which theoretically has worse bullet speed manages to land shots at mid to long range, but LC-10 misses all its shots because of the stupid bug which devs don’t care to fix.
Loadout stats show the bullet speed of LC-10 after equipping the task force barrel is 875 m/s, but the actual value is around 400 m/s, making this smg the worst in codm history.
