The mastery system requiring exclusively headshot kills to progress is strange. Almost every other unlockable in the game involves just getting regular kills, so why should mastery be any different? While getting headshot kills is certainly harder, it is also far more tedious to obtain, especially with weapons that have poor accuracy or function in a weird way like the Bow. Forcing headshots also gatekeeps players who aim for the torso out of getting mastery, which forces players to change their playstyles completely and forgo the consistent damage of torso shots for the inconsistency of trying to hit the much smaller head hitbox (which once again is made even harder by certain weapons' poor accuracy). How does 1 headshot kill show more "mastery" of a weapon than 50 normal kills?

In my opinion, mastery should be changed to simply require a large kill count to obtain. Maybe 500 ish kills on a weapon to master that individual gun, increasing or decreasing based on the weapon (ex. Pistol types require only 250 kills while an AR type would need 500 or more). If the headshot kills are so important, they could also be reworked into counting as 1.5 kills towards gun mastery. That way mastery is much less tedious, will progress more naturally, and doesn't force people to change how they play just to obtain it.
