Welcome to ASC.
First things first you've got a little bit of homework to start before you actually get moving along into the airsoft world. The term home work may not sound appealing but its definitely knowledge worth knowing. No questions involved, just some light reading.
That should be enough to get you rolling. That may seem like a lot of information but you don't have to read it all at once, however down the road it will definitely become useful to you. We also have a FAQ section as well if you have any more questions that require answers.
