Saying its a big NO is not quite true.
Bisley have a designated pistol and vintage range which is used for use of low powered air rifles these include air soft.
The only stipulation is no ball bearing type ammo only the little plastic balls and not automatic firing semi auto is fine. Everyone in the area MUST wear safety goggles . Nothing looking like a person to shoot at.
Also try to clear up to leave the area safe.
We have a couple of persons play but its not taken up as well as normal air rifles/pistols.
