Overview The XM8c is good at close-quarters combat. It is ideal for when the enemy surprises you. It is not recommended to bring this as your only gun, however. You should usually bring the XM8C when you have two weapons slots, and bring an accurate gun like the MP5, or ASVAL. If you cant afford it, don't worry! The XM8C is okay at medium range and long if you tap-fire.
