KING

A king is born.

With the all-new FX King we strive to keep pushing boundaries and keep innovating in many different ways. The FX King is a powerful and pure hunting rifle ready to dominate the hunting fields.

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.

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.

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

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.

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 flash- lights, bi-pods and more.

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.

All that 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.

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 gorgeous color 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!

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.

Note: Muzzle energy listed in the specifications of each rifle is for maximum setting. Due to differences in regulations the rifle is often produced with a lower muzzle energy from the factory. Contact your dealer for more info about muzzle energy in your region.
