MP5K

Our first weapon is MP5K. This weapon is one of the default weapons in the game.
This weapon is known for its high damage and average rate of fire for its class.

Shots to Kill: 3 Close/5 Far
Rate of Fire: 750 rounds per minute
Magazine Size: 30 Normal/45 Extended
Reload Time: 2.90 seconds

Secondary:

CZ75 is a good secondary weapon choice. If you happen to run out of ammo with your MP5K (which happens a lot if you don't use Scavenger perk), this is the best choice for its high magazine size.

Attachments:

Primary Weapon: Grip is the perfect attachment for this weapon, It reduces the high recoil of the MP5K. If you are using Warlord perk, I suggest using Extended Mags and Grip.



 

Secondary Weapon: Extended Mags is the best attachment for CZ75, increasing its magazine size by 18.

Perks:

Perk 1: I suggest using Scavenger if you are using the Rapid Fire attachment, It's highly effective on weapons that has a high firing rate. MP5K does not have high firing rate so I also suggest using Lightweight for rush types.

Perk 2: I suggest using Sleight of Hand, this is useful for this weapon because you have to reload almost every time you fire. If you are using the Extended Mags attachment, I suggest you use Steady Aim for more accurate hip fire.

Perk 3: Hacker is by-far the best choice of perk for the 3rd perk slot. It lets you see equipments through walls, good for room rushing, in case they have a claymore planted you can disable it before entering the room.

Equipment and ETC:

For Equipment, I suggest using Motion Sensor, it helps a lot to know where your enemies are and where they are going.

For Tactical, use Flashbang. It blinds your enemies completely making them completely defenseless, but effect only lasts 3-4 seconds so you have to be fast and aware of where the affected enemies are.

For Lethal, use Frag Grenade. It's good for clearing campers in a room, and the fact that it bounces of the wall is very helpful, meaning you could just throw the grenade and make it bounce of the wall in case there is someone camping inside a building facing the entrance.

Killstreak  Rewards:

This is a good choice for a killstreak reward, Spy Plane is very useful for rush type players, and you get it only for 3 killstreak.

Care Package is extremely useful for this class setup. You need to have a lot of ammo when using sub machine guns, and care packages sometimes gives useful killstreak rewards.

Blackbird is very useful for this class setup. You don't need killstreak rewards like Napalm Strike, Rolling Thunder, and other killstreak rewards that could kill because you and your gun will be doing most of the killing. It helps a lot when you see where your opponents are and which way they are facing so you could plan a good attack strategy.

This gun specializes in small maps like:

Nuketown

Summit
