MP5A4

The MP5A4 is a decently powerful but underused weapon. It has poor performance at longer ranges but can sometimes do just as well as an Assault Rifle at closer ranges depending on how well you can control the recoil. It is the most expensive of the 3 SMGs with a 15 High Quality Metal requirement and 1 SMG Body.
At close ranges, just like other pattern weapons you will focus heavily on the target's movement, however with the fast firing speed of 600 BPM you will sometimes have a hard time staying on target. Remember to not crouch at close ranges as you will make yourself vulnerable with the slow movement speed.
At longer ranges you will likely need to crouch, however with the slow velocity you can sometimes have trouble hitting targets and cheaper weapons such as the Semi-Automatic Rifle or Python Revolver will be able to compete against you.
Overall the MP5 can be a great gun and a decent replacement for the AK if you don't have rifle bodies, however the more cost efficient alternatives such as the Semi Automatic Body and Python Revolver can do just as well depending on the situation.

Pros ::: Easy to learn --- Satisfactory Mid range and good Mid to low and low ranges --- Good DPS --- It is versatile compared with the other SMGs
Cons ::: Expensive to craft --- Really low durability
Tips ::: The Arctic Wolf MP5 is the exact mix between the Custom SMG and the Thompson, getting a good DPS, good Damage and Good range (as a SMG). Also, his recoil is easy to learn and control. Different than the Custom SMG, the MP5A4 continues to maintain his value till the evolved game, trading really well agains't a AK-47 From Hell at lower ranges.

Quick rate of fire and medium damage, might not be able to outclass the Assault Rifle at range, but in close quarters this gun is a beast with an impressive 600 RPM! Being able to outclass most opponents if you hit your shots. Being an expensive smg at the cost of 15 High Quality Metal and 1 SMG Body.

I highly recommend this weapon with tons of bullets when doing a cargo ship raid.
