I would like to know if anyone has any experience ordering form them? I'm looking to get a Roni Carbine kit for the G18c I've recently bought, but nowhere in the UK sells them apart from Wolfarmouries who said they'll be in stock in several months. I know there are other carbine kits available, but the Roni kit can hold a WE G18c and none of the other kits state this (it's usually either KSC/KWA or TM Glocks that are mentioned to be used with them).
