James Tarrant, 66, from Essex, walked into a police station in Breda in the Netherlands on Saturday, the National Crime Agency (NCA) said.
He fled the UK after being arrested in 2009 when drugs, a gun and cash were found at a house in Waltham Abbey.
He was jailed for 15 years in his absence. Extradition proceedings have begun to bring him back to the UK.
The Metropolitan Police first detained Tarrant after finding cannabis blocks, two kilos of cocaine, a handgun, ammunition, body armour and approximately Â£5,000 at a property in Essex.
But he disappeared while on conditional bail.
Tarrant was one of eight "most-wanted" British criminals thought to be hiding in the Netherlands, and was featured on BBC programme Crimestoppers in December.
Dave Allen, head of the NCA's international crime bureau, said: "These fugitives really do have nowhere to hide and I would urge any of the remaining individuals to save yourself the trouble and hand yourself in."
Tarrant was arrested as part of Operation Return, a joint NCA, Crimestoppers, Bel M (Dutch Crimestoppers) and Netherlands law enforcement scheme to locate UK fugitives believed to be hiding out in and around Amsterdam.

Doug Paulley, from Wetherby, was denied access to a First Group bus when a woman with a pushchair refused to move.
Senior judges overturned an earlier ruling which said the firm's wheelchair policy was discriminatory and breached the Equality Act.
Mr Paulley has now lodged permission to appeal papers with the Supreme Court.
According to the appeal papers the Court of Appeal's decision was "wholly inconsistent with the policy of the Equality Act 2010".
Mr Paulley said he was prepared to take the case "as far as it needs to go".
"Disabled people chained themselves to buses in the 1990s to make sure accessible buses were put on routes, but there's no point in having them if you can't use them," he said.
In 2013 Leeds County Court ruled First Group's "first come first served" policy was unlawful and said disabled users should have priority access to wheelchair spaces.
However, last year the Court of Appeal said the "proper remedy" for wheelchair users to get improvements was to ask Parliament.
A spokeswoman for solicitors Unity Law, which represents Mr Paulley, said First Bus Group had indicated it objects to the application.
She said a panel of Law Lords will have to consider whether to allow the appeal.
Mr Paulley's case is being supported and funded by the Equality and Human Rights Commission (EHRC).
A spokeswoman said: "This case is of enormous importance to the thousands of wheelchair users who may wish to use public transport such as buses without having the anxiety of being told they cannot travel because the space is being occupied by buggies."
First Group told the BBC it was preparing a response.

The dramatic victory draws Higgins, 40, level with Ronnie O'Sullivan and to within one of Steve Davis's total for ranking tournament wins. Fellow Scot Stephen Hendry leads the way with 36.
England's Martin Gould, 33, playing in only his second ranking final, made a break of 138 in the 11th frame.
But Higgins held his nerve in the decider to take the £36,000 prize.
World-ranked 26 Gould, also helped by a break of 101 in the third frame, led 4-2 before the pair reached the interval locked together at 4-4 with Higgins managing a 112 in the seventh frame.
The Scot, ranked 13 in the world, then took three of the first four frames in the evening session.
Gould hit back to make it 7-7 before the next two frames were shared with the Londoner taking it into a final frame.
But Higgins - whose last tournament win was the Welsh Open in February - responded with a break of 89 to claim the first ranking title of the season.
