I was looking for the guide. Searched around a lot in different forums. Found this place luckily.
I know there are still newbies around looking to buy scopes.
I got a long range scope from Bushnell. Don't repeat the mistakes As I did.
Its really not worth it specially if you are starting out to go for 18x zoom. With great maginfication comes great vibrations hahaha.
Anyways, I ordered a NIkon P223
