Can someone who understand the topic please post about the different types of scopes and when it's best to use what?  There are so many and for me personally it is very confusing trying to figure out the best scope for the best situation.  I sometimes do better with just plain iron sights when it seems I would be better with something with magnification.

Help?  Please?

It's just personal preference,  really. Any scopes under 6x will not have glint.  Some low power scopes have nice dot patterns,  but block to much of your view.  Makes me glad we can use those canted sights.

I'm sure this isn't really the answer you're  after,  but trial and error is your best bet. The Battlefield wiki has views of all the sites.

Abram is right it is personal preference but also practice and persistence.
I use iron site mainly now but if sometime I use the 7x scope
