Airsoft is very much like paintball, only a bit more realistic I suppose since the guys use replica guns which fire those little plastic bbs. All about stratergy & defeating an enemy in a simulated combat environment.
www.arniesairsoft.co.uk/forums is a great site, loads of guys from all over the world. I have to agree though, upping the firing rate is cool, but it will ruin the internals much quicker so I would upgrade the gear sets and pistons before they fly apart, unless they are already upgraded that is....
