What Our Customers Say
Fun & worth the money
"Tips for new players: buy tickets ahead of time online, use white bio bbs, and use real eye protection not ballistic sunglasses. The field is well managed and has a positive culture! hard to find a field as good as Fox Airsoft, I'm gonna start going there every week."
