FX King 600 Brown Airrifle


The FX King 600 Brown is a remarkable PCP air rifle. Built on the foundation of the FX Dynamic, the King model distinguishes itself with a GRS stock and a 9 MIL/30 MOA scope rail, making it perfect for long distance shooting.

GRS stock
One of the standout features of the FX King 600 Brown is its GRS stock. The Norwegian firm GRS is well-known for their ergonomic and multi-adjustable laminated stocks. Being laminated, the stocks are less susceptible to slight warping, as normal wooden stocks can be under influence of temperature and humidity. This makes for a higher accuracy. Both the cheekpiece and the butt stock can be adjusted in fine steps without the need for tools. Two easy to operate push buttons are integrated in the stock design. And have you seen the grip? With finger grooves and slight angle, this must be the most ergonomic FX-stock to date.

Impressive engineering
The FX King 600 Brown showcases exceptional engineering, meticulously designed to facilitate optimal airflow. All its components work in perfect harmony, ensuring swift and efficient air delivery the moment you squeeze the trigger. Let’s explore the key engineering highlights:

Regulator: The single AMP MKII regulator stands out with its dedicated pressure gauge and precise adjustability. It enables you to fine-tune the pressure derived from the 250-bar bottle (480 cc, equipped with its own pressure gauge) to achieve the ideal plenum pressure for your chosen ammunition.

Plenum: Inside the plenum, regulated air is readily available for the next shot. The FX King features a substantial 156 cc Magnum XL plenum around the barrel, providing plenty of air for even the largest and heaviest slugs.

Block: The air rifle boasts an extra-large breech in the block, designed to accommodate slugs up to 13 mm in length. This is a strategic move, as the FX King is optimised for slug usage. The High Power/Short Impulse one-piece valve inside the block ensures a significant and rapid airflow.

Quick Tune System: Fine-tuning is made easy with the hammer spring preload adjustment, featuring macro and micro adjustments. With the macro adjuster, you can make quick progress without the need for prolonged turning of the wheel. After that, you can start finetuning with the micro adjuster. A clear scale enables precise setting selection.

Superior STX: The renowned Superior STX barrel system includes a changeable Superior STX Heavy liner with externally pressed rifling. This meticulous design ensures a smooth interior barrel surface and perfect sealing around the projectile.

Functional design
Every aspect of the FX King 600 Brown design is dedicated to achieving ultimate accuracy over medium to long distances, with a very strong focus on ergonomics. The adjustable 2-stage match trigger is known for its refinement, offering angle, distance and height adjustments for the blade. And of course, the two stages can be adjusted to suit your preference.

For those who prefer, the short throw cocking lever can be switched from one side to the other. The PCP rifle features two Weaver/Picatinny accessory rails on the sides to mount accessories such as a light or bipod legs.

To meet the requirements of long-distance shooting, the FX King includes a 9MIL/30 MOA Weaver/Picatinny scope rail that slightly slants forward. This feature expands the adjustment range of your rifle scope for long-distance shots.

Please note: The FX King 600 Brown comes pre-adjusted in an average state of tuning for average use. The maximum power stated in the specifications can be reached by using the multiple adjustment options on this air rifle, combined with the optional available tungsten hammer.
