What’s the ideal amount of guns to carry at once?

Right now I’ve got an AK 74, SG5-K, BK-133 and an Mlock-91, all at once. I feel like this is wayyy too much but for some reason I don’t want to drop any of these guns lol, maybe the BK-133 if I found a sniper rifle or something. But I’m way too attached since I’ve had these guns for a while... But I’m curious, how many guns do you guys carry at once? Or what’s the most you’ve carried at once?
