5 Points For Standard Magazine

It’s true for pretty much every “compulsory” attachment, there’s a minimum number of points for each of them, even iron sights.

But you have to assume they calculated the available points based on that and balanced accordingly. If you made all those basics attachments zero, you’d also have to lower the max number of points down to 80 or something to get the same balance. 

I'm really surprised why devs didn't make the iron sights 5 point.
