Founding date, headquarters, ownership and warranty terms come from FX's own site, Wikipedia, and a Hard Air Magazine warranty report. Current models and prices come from Airgun Depot's live FX catalog. My own M4 setup and hunts are noted where they're relevant, and are clearly marked as first person.

What does FX Airguns make?
FX is a Swedish PCP specialist, and everything it sells is precharged pneumatic; there are no springers or CO2 guns in the lineup. The rifles share a family trait: adjustable regulators, adjustable power wheels, and (on most models) swappable calibers and barrel lengths, so one action can be reconfigured instead of replaced. That's the same flexibility that let Utah Airguns turn my M4 into a dedicated slug rifle with a heavy slug liner, slug power kit, high-flow transfer ports and a tungsten hammer weight, without buying a different gun.
Current lineup
| Model | Type | Calibers | Typical price | Best for |
|---|---|---|---|---|
| Impact M4 | Modular bullpup, swappable barrels | .177-.35 | From about $2,195 | Hunters who want one platform tuned for slugs or pellets at any range |
| Panthera MkII | Premium bullpup | .177-.30 | About $2,000-$2,100 | Buyers who want Impact-level build quality with different ergonomics |
| Leopard | Sidelever sporter, tube or bottle reservoir | .177-.30 | About $1,500-$2,000 | Hunters who prefer a traditional stock over a bullpup |
| Dynamic MkII | Thumbhole sporter | .177-.25 | About $2,000 | Field target and hunting in a more conventional shape |
| DRS MkII | Compact bullpup | .177-.25 | About $1,000-$2,900 by trim | Buyers who want FX build quality below Impact money |
| King | Big-bore bullpup | .35-.50 class | About $2,000+ | Hog and larger-pest hunters who need more energy than .22-.30 |
Prices move with sales and configuration, so treat these as starting points and check current listings before buying. FX also sells the compact Wildcat and value-oriented Dreamline bullpups; both are current models, but I didn't find a stable US price to quote here, so check a retailer directly.
Best FX picks for hunting
- Impact M4 — the pick if you hunt regularly and want the range and modularity to justify the price. It's what I run, and it's the rifle behind every hunt on this site.
- Leopard — a strong alternative if you want FX accuracy without a bullpup's balance and trigger-reach differences.
- King — the FX to look at for hogs or larger pests, where .22-.30 caliber energy runs short.

Pros and cons
Good fit
- Hunters who'll use adjustable power, regulators and slug tuning
- Shooters who want one action to cover multiple calibers
- Anyone chasing top-tier accuracy at 50-130+ yards
Look elsewhere
- First-time PCP buyers — see my first PCP buyer's guide instead
- Budget shoppers; most current models run well over $1,000
- Anyone who wants a rifle that's finished tuning out of the box
How FX compares
Against Daystate, FX leans on mechanical regulators and power wheels you tune by hand, where Daystate's Red Wolf and Delta Wolf use computer-controlled, electronically metered valves. Against Air Arms, FX trades some out-of-the-box simplicity for far more adjustability; Air Arms rifles are typically accurate the day they arrive, while FX rewards someone who wants to chase a tune. Against AirForce, the contrast is sharper still: AirForce builds simple, largely unregulated big bores in Texas, while FX builds regulated, multi-caliber precision rifles in Sweden. My own dove hunt comparing an FX M4 against an AirForce Texan .257 is a real-world look at that difference: FX Impact M4 vs AirForce Texan .257.
Verdict
FX earns its price for hunters who'll use the range and tuning it offers. If you're buying your first PCP or hunting inside 40 yards on backyard pests, a mid-tier rifle does the same job for a lot less money. If you already know you want slug-level accuracy at distance, FX is one of the few brands built specifically for that.

FAQ
Is FX Airguns a good brand?
Yes, for hunters and target shooters who want a tunable, modular platform and are willing to pay for it. FX rifles like the Impact M4 lead independent accuracy testing and handle slugs better than almost anything else on the market. They're not the right first PCP: the regulators, power wheels and shroud systems reward tuning knowledge a beginner doesn't have yet.
Where are FX airguns made?
In Mariestad, Sweden, at FX's own factory. FX has made its own barrels in-house since 2005 rather than buying them from an outside barrel maker, which is part of why its rifles have a reputation for shot-to-shot consistency.
Who owns FX Airguns?
FX Airguns is privately held by its founder, Fredrik Axelsson, who started the company in 1999. There's no parent conglomerate behind it, unlike some UK and Turkish airgun brands.
What is the best FX Airguns model for hunting?
The Impact M4 is the standout: a modular bullpup that swaps calibers and barrel lengths, runs a fully adjustable regulator, and handles slugs as well as anything on the market. For a simpler, non-bullpup hunting rifle, the Leopard sidelever is FX's sporter-stocked alternative.
Is the FX Impact M4 worth the money?
For a hunter who'll actually use the range and tuning options, yes. It's my primary hunting rifle, slug-tuned by Utah Airguns for 40.1gr ACE FRAG slugs at about 950 fps. For a full cost and performance breakdown, see my FX Impact M4 review and my exact slug setup.
What is FX Airguns' warranty?
FX backs its rifles with a 3-year warranty through its US distributor, up from the previous 1-year term. Register the rifle after purchase to activate it, and keep your receipt.
Is FX a good brand for a first PCP?
Not usually. FX's whole lineup is built around adjustability, from power wheels to externally adjustable regulators, which is a feature a beginner doesn't need and can mis-set. Start with a simpler regulated PCP and step up to FX once you know what you want to tune. My beginner PCP comparison covers rifles built for that first step.
What calibers does the FX Impact M4 come in?
The M4 swaps between .177, .22, .25, .30 and .35 with a barrel and liner change, so you're not locked into one caliber. My own M4 runs .22 for small game; .25 and .30 add energy for bigger pests and hogs.
