How many magazines per EBR (AR, AK, FAL, M1A...) do you feel you need to have as the bare minimum? Let's say you lived in one of the freedom-challenged states like Kali where getting decent new ones is difficult. How many would you own per rifle?
Good point, but some people move faster when their life depends on it.You only need what you can physically carry and manuever with. So grab your rifle and gear and start doing wind sprints from tree to tree or building to building. You will quickly decide how many magazines are sufficient.
Depends on the situation. War? Yeah, a helmet and armor would definately come in handy. Zombies? Just extra weight.As a side note, unless you are wearing Class IV body armor and a helmet, you probably won't be using more than one mag.
