Fortnite Challenges: Here Is the Guide To Season 5 Week 4 Challenges

The fourth challenge is to Deal 500 damage with a sniper rifle to enemies.

Completing this gives the user 5 battle stars which if you ask me is not fair for such a tedious challenge.

An easy way to complete this one would be to equip a sniper rifle with you always and once you've knocked out an enemy or you see an enemy knocked out by anyone else , box them in and make sure you land a sniper bullet on the fallen enemy.
