A medium damage machine gun.
The MP5A4 (MP5) is an automatic weapon in Rust. Its default ammo is the Pistol Bullet. It deals 37.5 damage per shot at 600 shots per minute from its 30-round magazine. You craft it at a Level 3 Workbench, and its blueprint costs 300 scrap to research.
About the MP5A4
A full reload takes 4 seconds, and switching to it takes 1.6 seconds. It can switch between burst fire and fully automatic fire. Aiming down the sights narrows its spread from 3.5° to 0.5°, 7 times tighter than firing from the hip. Its 12 compatible attachments include a silencer. Mounted in an Auto Turret, it deals 35% of its normal damage.
There are 3 kinds of ammo for it: Pistol Bullet, Incendiary Pistol Bullet and HV Pistol Ammo. With the remaining ammo type, its damage per second is 163 for the HV Pistol Ammo. The HV Pistol Ammo flies fastest, at 360 m/s, and the Incendiary Pistol Bullet slowest, at 203 m/s.
From full condition it fires 600 shots with the Pistol Bullet before it breaks, which is 20 full magazines.
On the tech tree it sits behind 5 other unlocks: Incendiary 5.56 Rifle Ammo, HV 5.56 Rifle Ammo, Weapon Lasersight, SKS and Reinforced Glass Window. In all, 17 loot sources drop it; the full list of where it drops gives the chance for each.
