Swedish maker FX Airguns has spent two decades building a reputation as the innovation house of the airgun world, and its rifles routinely top the wish lists of British airgunners. The FX King is one of the range’s most interesting propositions: a rifle that takes the accuracy pedigree FX built with its flagship models and packages it in a cleaner, more traditional sporting format. Searches for the FX King for sale in the UK have been picking up, so this guide covers what the King offers, who it suits, and what to consider before buying.
Where the King sits in the FX range
FX’s line-up can be dizzying: Impact, Crown, Panthera, Dreamline, Wildcat, DRS, each aimed at a slightly different shooter. The King’s role is the classical sporting rifle of the family. Where the Impact is a modular, tactical-styled platform bristling with adjustment, the King wears a conventional stock, carries its air reservoir neatly under the barrel, and points like a traditional hunting rifle. Think of it as FX’s answer to the shooter who wants the brand’s celebrated barrel technology and regulated consistency without the laboratory aesthetic.
That positioning matters in the UK, where many airgunners still prefer a rifle that shoulders like a sporter for roving hunts and hide work, rather than a benchrest instrument. If you have admired FX accuracy but been put off by the look of the Impact, the King is the model FX built for you.
Technology that made FX famous
The King draws on the same core technology as its stablemates. FX’s interchangeable liner barrel system allows the bore to be matched to different pellet and slug weights, and its regulated action delivers shot-to-shot consistency that few rivals match at the price. The side-lever cocking action is light and positive, feeding from a rotary magazine, and power adjustment lets owners tune the rifle to their quarry and conditions.
For British buyers, the crucial point is that the King is available in sub-12 ft·lb guise, which can be owned without a firearm certificate in England and Wales, alongside FAC-rated versions for certificate holders who want more power. If you are unsure how the law treats air rifles at different power levels, our UK air rifle laws and licensing guide sets out the essentials, and Scottish readers should remember an air weapon certificate is required north of the border.
How it shoots
The King’s calling card is consistency. A regulated FX action holds its velocity across the charge, which translates to tight vertical spreads at range, exactly what hunters need for confident head shots on rabbits at 35 yards and what target shooters need for clean cards. The side-lever makes follow-up shots quick and quiet, and the shrouded barrel keeps muzzle report neighbour-friendly, an increasingly important consideration for permission holders shooting close to houses.
Pellet choice still matters, as it does with any PCP. The liner system gives the King unusual flexibility here, happily shooting conventional diabolo pellets or, in appropriate configurations, heavier slugs. Our explainer on airgun slugs vs pellets covers the trade-offs if you are weighing the two.
The King vs the Crown and DRS
Within the FX family, the King’s closest relatives on the UK market are the Crown and the DRS, both of which draw strong interest from Rightgun.uk buyers. The Crown remains the connoisseur’s choice, with a wider spread of adjustment and a price to match. The DRS takes the opposite path: a stripped-back, robust hunting tool at a friendlier price point. The King threads between them, more traditional than either in its stock work, with the refinement of the Crown’s internals but a simpler control set.
Buyers comparing across brands should also look at the British-built competition. The Daystate Red Wolf and Air Arms S510 both compete for the same premium PCP money, and our reviews of the Daystate Red Wolf and the FX Impact give useful context on how FX’s approach differs from the traditional English school.

Buying an FX King in the UK
New Kings sit firmly in the premium PCP bracket, with final cost depending on calibre, configuration and whether you opt for the sub-12 or FAC version. The second-hand market for FX rifles is active, the brand holds its value well, and used examples are typically snapped up quickly when they appear.
When buying used, ask about the rifle’s service history and whether the regulator has been adjusted from factory settings; a rifle that has been heavily tinkered with is not necessarily a problem, but you want to know what you are getting. Check the air cylinder for its test status, inspect the liner and crown for damage, and if possible ask the seller for chronograph figures, a consistent string is the best evidence of a healthy regulated action. Remember that sub-12 ft·lb rifles must remain below the legal limit, so a chrono check protects you legally as well as financially. Our second-hand air rifle buying guide covers general condition checks that apply to any pre-owned PCP.
Who should buy one?
The King suits the serious UK airgunner who hunts as much as they plink: someone who wants genuine long-session accuracy for vermin control, values a rifle that carries and shoulders like a sporter, and is prepared to pay premium money for premium consistency. Newcomers to air rifle shooting may be better served starting with something simpler; our complete air rifle buyer’s guide walks through the options, but for experienced shooters stepping up, the King is a rifle you buy once and keep.
Frequently Asked Questions
Do I need a licence for an FX King in the UK? Sub-12 ft·lb versions can be owned without a certificate in England and Wales by those aged 18 and over. FAC-rated versions require a firearm certificate, and all air rifles in Scotland require an air weapon certificate.
Is the FX King accurate? Consistency is the King’s strongest suit, the regulated action and FX’s barrel system deliver the shot-to-shot uniformity the brand is known for. As with any PCP, results depend on matching the right pellet to your barrel.
What calibres does the FX King come in? UK examples are most commonly found in .177 and .22, with larger calibres appearing on FAC-rated rifles. Check the specification of the individual rifle when buying, particularly on the used market.
