FX King 500 Brown

The FX King 500 Brown is an impressive PCP air rifle. Developed on the basis of the FX Dynamic, the King distinguishes itself with a GRS stock and a 9 MIL/30 MOA scope rail, making it perfect for use at medium to long distances.

GRS stock
One of the distinguishing features of the FX King 500 Brown is its GRS stock. The Norwegian company GRS is known for its ergonomic and multi-adjustable laminated stocks. Because laminate does not warp (bend slightly) like a wooden stock can under the influence of temperature and humidity, maximum accuracy is guaranteed. Both the cheekpiece and the butt pad are adjustable in small increments without the need for tools. Two easy-to-operate push buttons are integrated into the stock for this purpose. And have you seen the grip? With finger grooves and a slight tilt, this should be the most ergonomic FX stock.

Impressive Technology
The FX King 500 Brown is an impressive piece of technical ingenuity, carefully designed to create the most efficient airflow possible. All components are perfectly coordinated, guaranteeing fast and efficient airflow the moment you pull the trigger. Let's take a look at all the technical highlights:

• Regulator: The single AMP MKII regulator stands out with its own precision manometer and refined adjustability. It allows you to fine-tune the pressure from the 250 bar air cylinder (480 cc, equipped with its own manometer), so you can build up the ideal plenum pressure that suits your chosen ammunition.
• Plenum: Inside the plenum is the regulated compressed air ready for the next shot. The FX King has a 62 cc Macro plenum around the barrel, with sufficient air supply to shoot even the largest and heaviest slugs.
• Block: The air rifle has an extra-long breech in the block, designed to load slugs up to a length of 13 mm. A strategic decision by FX, indicating that the King is truly optimized for slugs.
• Quick Tune System: Fine-tuning is a breeze with the hammer spring preload adjustment. There is a macro adjustment and a micro adjustment, so you can make large changes first without endless turning, and then achieve the perfect setting with fine-tuning.
• Superior STX: The well-known Superior STX barrel system includes a replaceable Superior STX liner with externally pressed rifling and lands. This ingenious design ensures a very smooth surface inside the barrel and a perfect seal around the pellet or slug.

Functional Design
Every aspect of the FX King Brown 500's design is focused on achieving unparalleled accuracy at medium and long distances. At the same time, there is a strong focus on ergonomics. The adjustable 2-stage trigger is known for its refinement and broad adjustability.
