MG42
Aside from Snipers there is two way to have an easy kill on long range enemies, cheating which is something a lot of people do but is not fun and I'm not gonna talk about that here, and MG42!
Why MG42?!
Let's look at what we need to have a good long range gun in BR:
- No Aim Spread.
- No Vertical or Horizontal recoil.
- Decent Damage.
- High Fire rate so enemies won't have enough time to hide.
Good thing with MG42 is that it can have all of above with the correct attachments and perks. Take a look at this example below.

- Barrel: VDD890 MM 32M Luftschutz
