The Kraber is the worst weapon in the game in a regular players hand. it is a bolt action sniper with bullet drop and fire projectiles, meaning you need to lead your shots, however it has one advantage that makes it incredibly dangerous. It oneshots pilots no matter what. hit craig in the foot? dead. sam in the hand? dead. dave in the head? mega dead. if you can hit your shots with this piece of trash, you become an unkillable god.

To learn how to win with this, boot up a private server in attrition and get shooting. for attachments start with zoom scope with extra ammo and gun-ready sights. I'd start with simple stationary shots from rooftops, from as long a distance as you can manage, and once you start hitting more than you miss it's time to practice with pilots.

Pilots are a lot harder to hit than grunts, first off, so say goodbye to your K/D, second off, begin to practice hitting shots on pilots, don't aim for the head, as it doesn't matter, and learn to lead your shots based on distance. Distance and being in weird places will be your best friend, as the longer the distance between you and them, the more time you have to run if you miss your first few shots, and don't forget to run btw, as the Kraber has a very clear tracer for each shot. go for long range shots, this will force you to lead your targets and account for bullet drop properly. once you feel good about your long ranged sniping power, it's time to fargo all of that in favor of a much more infuriating approach

So now you can snipe from a distance, but i'll let you in on a secret, the Kraber is the best shotgun in the game, so let's discuss how to use it. First unequip the zoom scope, it'll just be slightly confusing, and who needs zoom when your target's always 12 ft. or less from you. for the best quickscopes, equip the default one. not the threat scope, you want a clean sight picture, and the extra mod slot. everything else can stay though, especially gun ready sights. now head back to a private attrition match and get practicing. to quickscope get close, like really close, especially at first, allign the center of your screen where the enemy should be, then zoom and fire. i find the best luck with this while sliding. the farther away you can do this the better, although past mid range it isn't very reliable and you should't expect to land those without taking time to zoom, and line up your shots, remember with pilots you may still need to lead your shots, even at ridiculously close ranges. from here you can practice in real games if you feel like it.

The Kraber is hard to use and it's supposed to be that way. the only way to truly master it is with time, so practice, pilots, grunts, reapers, get those gens, and if you stick to it you will eventually be the leading cause of suicide for players on the enemy team.
