FX has become one of the most talked-about names in UK air rifle shooting. Pest controllers rate them, field target shooters build whole competition set-ups around them, and a good number of hunters now treat an FX as their default PCP. The catch is choice. The King, the Impact and the Crown all appeal to the same kind of buyer, and it is easy to spend weeks reading threads without getting any closer to a decision.
This guide compares the three at a practical level: what each is best known for, who tends to buy it, and what to look at when you are shopping for a new or used example. We have deliberately avoided exact specifications and prices, because FX models are offered in several calibres, lengths and configurations, and values change with condition and extras. Always confirm the details in the listing.
What the FX brand stands for
FX Airguns is a Swedish manufacturer with a reputation for modular, tuneable PCP rifles. Features that run through much of the range include regulated air systems, quality barrels and a design philosophy that lets owners adjust or upgrade parts over time. That modular approach is a big part of the appeal: an FX can be tailored to a purpose rather than being a fixed package.
For UK shooters, the key legal point is the familiar one. Rifles that stay within the sub-12 ft·lb limit can be owned without a certificate, while more powerful rifles fall under firearms law and need the right authority. Always make sure the rifle you are considering is set up to suit your legal position, and ask the seller if you are unsure.
If you want an overview of the brand before comparing models, our FX airguns range guide is a good starting point.

FX King: The all-rounder people ask about
The King is one of the most searched FX names for a reason. It is widely seen as a capable, well-rounded rifle for shooters who want one PCP to cover hunting, pest control and general accuracy. Owners tend to praise it for being straightforward to live with, and it appears regularly in both new and used listings.
If you want to understand its strengths in more depth, read our FX King air rifle guide. The short version is that it suits buyers who value versatility over specialisation.
When you are looking at a King, ask which calibre it is chambered in, whether it is regulated, and which stock and accessories are included. Those details influence both how it shoots and what it is worth.

FX Impact: The modular favourite
The Impact is probably the model most associated with FX’s modular reputation. It has long been a favourite with field target competitors, long-range shooters and serious hunters who like to fine-tune their rifle. The attraction is that different parts can be swapped to change how the rifle behaves, and the used market is active because owners often upgrade.
That activity is useful if you are shopping second-hand, but it also means condition and history matter. Ask what modifications have been made, whether any parts have been replaced, and how the rifle has been maintained. A well-looked-after example with a clear history is worth far more to you than an unknown one.

FX Crown: The premium option
The Crown is generally positioned at the premium end of the range, with an emphasis on finish, ergonomics and refinement. Buyers who want a rifle that looks as good as it shoots, or who plan to keep their rifle for many years, often start here.
Because it sits towards the upper end of the range, used Crowns tend to be well cared for. Even so, do the same checks you would on any PCP: the condition of the barrel and crown, how the regulator and gauge behave and whether the magazine fits and feeds properly.
Our FX Impact, Crown and DRS comparison puts several of these models next to one another if you are still undecided.

How to choose between them
Rather than asking which rifle is best, ask what you will actually do with it. For all-round hunting and pest control on a sensible budget of time and money, the King is often where people land. For tinkering, competing or chasing small gains, the Impact’s modular nature gives you more to play with. For a rifle you intend to keep and enjoy, the Crown’s refinement is the draw.
Think about weight and handling. A rifle that feels great in a shop can feel very different after a day walking a hedgerow. Where you can, shoulder each rifle, check the cheekpiece and trigger reach, and think about how it will balance with a scope and moderator fitted.
Finally, remember the running costs. A PCP needs a way to fill it, whether a pump, a bottle or a compressor, and that equipment can change your overall budget more than the difference between two similar rifles.

Buying a second-hand FX safely
A used FX can be excellent value, but a few precautions are worth taking. Ask whether the rifle holds pressure and how long it has been since its last service. Check the barrel and crown for damage, and look carefully at the regulator, gauge and magazine. Confirm what is included, including magazines, bottle or fill adaptors, moderator and scope, as these can add up.
Look at the photographs critically. Marks on the stock are cosmetic; damage around the barrel or air cylinder deserves a closer look. If you cannot inspect the rifle in person, ask the seller specific questions and expect clear answers.
