Several weapons in Battlefield V give you the option to switch between two firing modes: single-shot and fully-automatic.
So far it looks like there are only four of this new type of collectable to find, which is certainly less than Rockstar's other fiendish scavenger hunts, like the broken radio antennas (opens in new tab) or movie props (opens in new tab). In-game, GTA 5 looks gorgeous on new-gen consoles.
