Prosecutor Dominique Laurens in Meaux, east of Paris, had already dismissed terrorism links but said today the man risks up to five years in prison and a fine of USD 82,000 if convicted.
The charges include acquiring and transporting arms and ammunition.
The man, who has not been identified, was detained Thursday with a female companion when he tried to bring the weapons into the hotel. The woman was cleared of complicity.
The man was expected to go before a court Monday, a statement by the prosecutor said.
