From my experience, especially online, there are 'waiver' descriptions stating something very similar to try and protect the retailer liability, i.e. "This is not a toy. If misused this could cause serious injury or death", etc. Unfortunately other than this, there isn't a whole lot that can be done to cover their asses other than forcing a waiver to be signed at the time of purchase. Most retailers don't really want to keep stacks of waivers on hand either though, so it's a double edged sword that one is..

Can't retailers have a clause that all legal responsibility ends after selling airsoft guns to 18+ individuals meaning whatever they do with it afterwards like handing it over to a minor, said retailer can't be punished by the law. Doesn't do much to protect the sport but at least it puts more emphasis on the actions of the purchaser. I honestly don't think there is a way to detect straw purchases unless it was in plain sight.
