So my understanding is that the scopes on long range weapons, and magazines in general are potent upgrades for certain weapons, more bullets means less time reloading. In a active firefight you may want those extra bullets or need that extra zoom to be more flexible or just see farther. While I think there are a few attachments that are a little expensive, I'd say overall I appreciate the limitation because otherwise, people would just slap all the best gear without considering why they do it besides some video. Yes people still do that because a lot of people mentally check out during their down time, but I think it is better to restrict what you could attach to stop everyone's loadout feeling the same or at least allow people to stand by their choices of why they took a lower zoom scope over a higher one, or justifying a certain grip type for their playstyle.
