Deadeye PSR sniper assignment

The deadeye weapon assignment requirements are absurd even getting the DMR was hard enough but possible with bot grinding. But getting 150 headshot kills over 200 meters is preposterous and should be adjusted to 100-150 meters because even in a firestorm server with severely nerfed bots with 10 minutes of trying I only managed to get ONE kill that met the requirements. Having to do all this to unlock one weapon is crazy.
