Hello,
Last summer (2025), I imported a RIF from a UK seller to France (without gas magazines as they were prohibited).
Both the seller and I asked a third party — Sam Liggat, Owner & Head Tech at Kingdom of Airsoft — to handle the shipping process to France (UPS not Parcel Force). The service was reasonably priced and the whole process went very smoothly.
French customs were noticeably more confident once I explained that the package had been shipped through an official airsoft store and confirmed that the item is an airsoft gun toy.
For future imports outside the UK, I will definitely rely on Kingdom of Airsoft again to assist with the shipping process to France.
