I've noticed Aliexpress gear on the whole has become faster, no doubt due to the VAT being paid at source, also noticed when I bought some HK gear that didn't require me to pay the VAT at source it arrived pretty fast as well, about a week.
Have to say since the change in vat and what not Aliexpress has become my default stop for most of my airsoft bits’n’bobs , don’t even look at gunfire or Taiwangun any more .
