Have you ever been in air cadets?
Im in air cadets and I have fired lots of weapons other than the shit you have mentioned.
The worst weapon I have fired is the .22.
Ive fired the L98, SA80 mach 1 and 2, PSG1 to name three.
As well as flying solo in a viking and two gliders that I dont know the name of.
And also I have done my Duke of Edinburgh (sp?) silver award.
I've met some of my best friends at air cadets.
Dont assume it is shit until you've tried it.
