A King has been crowned

With the all-new FX King FX Airguns keep pushing boundaries and keep innovating in a multitude of ways. The FX King is a powerful and pure hunting rifle ready to dominate the hunting fields.


Proven Block

At its core, the FX King inherits the same true and tested block of the Panthera/Dynamic that's capable of delivering a huge amount of power and energy. The FX king is an awesome pellets shooter without a doubt, but where it really excels is shooting slugs, thanks to its slug-based design and innovative valving. All while maintaining a slim and beautiful look as it sits in a custom-tailored GRS stock.


Over-the-Barrel Plenum System

With the large innovative over-the-barrel plenum system like you can find on other FX models the FX King can use the big volume to its advantage. Whether you want to shoot pellets or heavy slugs the FX King can handle it all while maintaining a sleek look in a traditional sporter stock.


Optimally Positioned Gauges

Dual-angled high-precision Wika gauges are set to monitor the bottle and regulator pressures. This way you can keep track of both pressures while shooting, even from the shouldered position out hunting. All so you won't miss that all-important shot.


Quick-Tune System

It is impossible to imagine a powerhouse like the FX king without the ability to tune it the way you want. Therefore, the quick-tune system was a must and is seamlessly integrated into the ergonomic GRS rifle stock. Adjustments can be made quick, repeatable, and precise.


Accessory-Ready

Even though this is a very classic sporter rifle we know you would love to mount accessories. So we have created accessory Picatinny rails on both sides of the FX King with the possibility to mount torches, bipods and more.


Handles Pellets & Slugs

With the deep magazine design adopted from the Panthera/Dynamic, the King can handle any kind of ammunition you throw at it up to 13 mm in length, pellets of any kind, shorter lighter slugs or heavy longer slugs are no problem.


30MOA Picatinny Scope Rail

All that is topped with a Picatinny scope rail that is 30MOA angled allowing you to have more usable elevation adjustments on your scope and reach out to longer distances with ease.


GRS STOCK

The King sits in a custom-tailored GRS stock, just like you would expect a King to wear a fine-tailored suit. Available in three superb colour options.

The Norwegian stock-making company GRS builds highly adjustable ergonomic laminate stocks with features like tool-less adjustments, a broad for-end and an ergonomic GRS grip, offset and angled, offering unsurpassed shooting comfort making the King stand out among the rest!


Comes with Hard Case

The FX King comes to you in a nice hard case with custom-cut foam that fits like a glove protecting your new rifle in transport and storage.

Monthly reload for Subscribe & Save Orders
Reload type: One Time Reload
Not a glamorous review, but a genuinely useful tip for Subscribe & Save users. I reload about $100 to my gift card balance once a month, a week or two before my S&S order processes. Amazon pulls each Subscribe & Save item as a separate transaction, which means 10+ individual charges hitting your bank account on before or on ship day. A headache for budgeting and a minor anxiety trigger if you're watching your account for unauthorized activity. Loading the balance first consolidates everything into one clean transaction. Your S&S order then pulls from the gift card balance rather than your card directly, and your bank statement stays tidy. The side benefit is built-in budget discipline. I set about $100 as my monthly Amazon ceiling - if my cart runs over, something gets pushed to next month. It's a simple system that keeps spending intentional without any extra effort. If you're a regular S&S user who wants cleaner finances and less ""wait, who charged this and what was that charge?"" moments, this is worth making a habit.

Great for Budgeting – Instant Balance and Easy to Use
Reload type: One Time Reload
I use Amazon’s gift card reload feature to plan my spending. It’s perfect when I know I want to make a purchase but prefer to set the funds aside first. I love that it’s immediate—no worries about pending charges or accidental spending from my card. It gives me peace of mind knowing that when I’m ready to buy, the balance is just sitting there, waiting. Pros: easy to use, instant balance update, helps with budgeting and avoiding overspending Cons: funds are locked into Amazon once reloaded, doesn’t count toward certain account requirements like review eligibility Overall, it’s a convenient and reliable way to manage spending on Amazon, especially if you like having control over your purchases.

I did this with a pay in 4. It made it super simple for a higher balance.
Reload type: One Time Reload
I’ve used this to reload my balance a few times, and it’s been simple and reliable. The process is quick, and the funds show up without any delays or issues. It’s a convenient option when you want to control spending or keep purchases separate without using a card each time. Everything is straightforward and easy to manage. I haven’t run into any problems with transactions or balance updates. It’s been consistent every time I’ve used it. Overall, it’s an easy and dependable way to keep funds ready to go without any hassle.

Easy to use. Perfect for items you might end up returning.
Reload type: One Time Reload
First thing to note is that this is easy to use. Select whatever amount you want, how often you want it (one time, a specific date, etc), and then click buy and confirm the payment method. I normally only have to wait a few minutes for the process to go through and get the funds added to my balance. I like using this option for the very rare times I order something that I'm not sure I'll end up keeping, such as buying shoes or other clothing. Items that say they're the same size might not fit correctly for some reason and I'll have to return it. I find the return process is faster and easier than using a card where I'll have to wait until the money is put back on the card.
