Corrected it for you. Largely it's because it's cheaper to have parts that will withstand 280fps with a 0.20g, and in some countries, airsoft guns have a 1 Joule maximum, suck as the UK. 1J is considered 330fps with a 0.20g BB. If airsoft is a worldwide market, it'd make sense to have products that can be legally imported and purchased by all markets. Aka. I doubt G&P are legal for import and sale into the UK, since they tend to shoot 425-430fps in stock form.
