Airsoft field is generally very competitive. You will not be happy after going there a few time with the beginner gun you picked. It's possible to get a good gun at the price you are referring to, but you have to know what you are doing and know you are getting a good deal.
I suggest you study up a bit on what is considered a good, competitive gun. Then look for a good deal on them. Keep in mind you'll actually need more than just the gun. The source below will help you make a list of everything you need.
I'm not even going to look at the links because it's impossible to find an airsoft gun to take to the field(arena) for under $90.... Look bud, if u buy gun between $60-80 u will embarrass yourself there. Please don't buy a cheap gun like that, it will break immediately and suck. The cheapest competitive gun ur gonna find is a lancer tactical m4 for around $95-100.
If you want to know more or have any questions then u can talk to me on the app "KiK" and I will answer all your questions
