So i'm wondering this again, why is weapon score a thing? Multiple weapon packs have made every base game weapon obsolete (sadly).
At this point the weapon score for rifles in particular doesn't make a bit of difference beyond bragging, the most useful scope in the game is unlocked pretty easily and nothing else is necessary once the hyperion is unlocked.
The main request here is to remove level and experience requirements from weapons, equipment, and ammo. The skill/perk points are enough of a reason to passively level up and earning the 90k to buy the .470 should be enough of a requirement to unlock it. Consider this a Quality of Life change, as it won't affect long term players and still make it easy for new players to get into the game and enjoy their favorite aspects easier
