The Task Force barrel is supposed to increase this weapon’s bullet speed by 75%, but it does not actually do so. After equipping the most important attachment for this weapon, the Task Force barrel, the bullet speed should be 875 m/s as stated in the loadout stats. However, the actual tested value is around 500 m/s, which makes this gun almost useless at mid to long range.
As shown in the video, you can see the LC-10 struggling to hit shots at mid range because of its bugged and poor bullet speed, while the BP-50 performs this task easily.
If this bug is fixed, the gun will become usable again.
