Should FPS limits be higher or lower?

Here in the States...I think lower.

I think they are fine as they are

Fine as they are in the UK. And at most sites changing them would mean changing the law first.

I think thats weapon dependant, like a bolt action sniper should be able to outshoot an AR anyday, but would be limited by its rate of fire. Here in ireland all fps is the same no matter the weapon

In the UK the change of limits would have to be change if legislation, any automatic airsoft rifle that exceeds 350fps or 1joule is then branded as an actual firearm

Here in the UK gbb should be lower!
