Hi Sam.
First of all welcome.
Also a great friendly bunch here at C.E.A
The guns we hire are £10 or there abouts for the day, a bag of BB's (3000 in a bag) £10 a day and green fees £20 for the day.
The club guns are M4 style ones and a fairly good.
The day starts at 10am but most people get on site about 9ish.
New guys are recommended to get there about 9 as there is safety stuff to run through.
Simon and Mark are the two main guys but you can also ask Vicky or Pete as they are both great guys and will help you with any question, however all at the site will help as much as possible.
Hope this helps
Cheers dude and hope to see on the battle field.
