The Best BK57 Class


  • Red Dot Sight
  • FMJ
  • Foregrip
  • Stock

The BK57 has a high rate of fire and good accuracy, with the red dot sight and foregrip this gun will obliterate opponents at range.

The Stock attachment will increase your mobility when aiming and FMJ will help you cut through any cover or objects in the way.


  • Fast Recover
  • Toughness
  • Hardline

Fast recover will help you regenerate health from prior gun fights faster to help you get back into combat.

Toughness will help reduce your flinch when shot, so you'll be able to shoot from long range and maintain your accuracy.

Hardline will help you reach higher streaks faster.


  • Grenade (Lethal)
  • Flashbang (Tactical)

The grenade is great for throwing down uncooked and blocking off areas for the opponent. The flashbang will disrupt enemy vision in an area to allow you to rush your opponents.


Operator Skill

  • Purifier

The Purifier will help you flush out enemies quickly in tight buildings or corridors.


  • UAV (400)
  • Predator Missile (700)
  • XS1-Goliath (800)

By playing aggressively, you can expect to die more often than normal. Aiming for lower killstreaks can really help you succeed.
