The FX King

Introducing the FX King, the ultimate traditional sporter-style air rifle for 2023. This model builds on FX’s reputation for innovation, quality, and exceptional performance to meet the needs of today’s airgun enthusiasts. The King features a classic laminate stock from Norwegian stock maker GRS. Combining power and adjustability with the innovative Dynamic block and quick tune system.

To be the best in the traditional sporter class, versatility is crucial. They now integrated the FX Quick Tune system into the King’s GRS stock, allowing shooters to fine-tune the rifle based on their personal ammunition needs. Whether you’re into field target, hunting, bench rest competition or backyard plinking, the King can handle it all.

The King is powered by FX’s revolutionary Dynamic Plenum, which provides consistent regulated pressure around the barrel. This increases rigidity to the overall platform. Dual-angled WIKA gauges on the left side of the block show bottle pressure and regulated plenum pressure at a glance. Other features include a 30MOA Picatinny scope rail, adjustable trigger, and side Picatinny rails. You can mount accessories on these side rails, such as flashlights, lasers, bipod legs, and more.

The King comes in two barrel lengths, 500mm and 600mm. The 500mm features the Superior Liner (except in .35 calibre) and the 600mm features the Superior Heavy Liner across all calibre options.


GRS Stock

This GRS stock is custom-designed for the King, hand-made in Norway, and truly fit for a King. Available in both right and left-hand configurations, the stock offers an ergonomic shooting experience. The unique angled grip provides excellent control over the rifle in different shooting positions. Meanwhile, the tool-free push button adjustments for both the cheekpiece and butt pad provide shooters with a tailored fit. Available in three different laminate colour options: Green Mountain, Hunter Brown, and Nordic Wolf.


The King comes in a high-quality hard case with custom-cut foam to ensure a perfect fit for your new rifle during transport and storage.
