Is there way to add recon scope effect without using a weapon modification? For example just having a recon scope effect default for a custom weapon without upgrading to a weapon with recon scope effect?

Have a look at the recon scope script.

Maybe that gives you some idea of how to implement it - however, I've noticed that the scope script throws quite a lot of exceptions to your Papyrus log if you're not careful.
