I call having a chest full of guns...........
Having no freakin guns!!!
LOL.
I keep a trunk or rack of each kind that I only use for special times like when a new season drops or something like that. Also a locker of glocks in Alfa and some shotguns in Alfa. I pretty much use only glocks in Alfa plus I use them anywhere else when I have more than I can store. I also generally use all my shotguns for the blind one.
Unless you absolutely don’t have a choice I’d save m16, uzi, and AK until you have some mods that help with stability. You waste a lot durability with your misses otherwise.
