Fireball squadron at bassets pole Near Sutton , just so you are aware , fireball squadron run their walk on days on the first Saturday of every month but at the moment they are running a booking only system due to Covid (August is full) NPF run their own Airsoft days totally separate from fireball I think booking for them is through the npf website , I can vouch for fireball it’s a great site and run well , there is also stormforce between rugeley and Lichfield if you can travel a little bit which is well worth a visit
