New for 2023, the FX King is the pinnacle of traditional sporter-style air rifles. Building on a legacy of innovation, quality, and unmatched performance, FX once again delivers a product designed to meet the demanding tastes of today’s airgun enthusiasts. The King brings together the power and adjustability of the innovative Dynamic block and quick tune system in a classic laminate stock from Norwegian stock maker GRS.

To truly be at the top of the traditional sporter class, the versatility to meet shooter needs is key. The FX Quick Tune system has been integrated into the King’s GRS stock. This gives shooters the ability to dial in the King based on their personal ammunition needs. Field target, hunting, bench rest competition, or backyard plinking, the king is capable of meeting any demand.

Fueling the King is FX’s revolutionary Dynamic Plenum. Currently featured in the FX Panthera and FX Dynamic models, this over-the-barrel plenum combined with the FX AMP MKII Regulator provides consistent regulated pressure around the barrel increasing 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 quick glance. Other features include 30MOA Picatinny scope rail, adjustable trigger, and side Picatinny rails for mounting all your favorite accessories (flashlights, lasers, bipod legs, etc.)

The FX King will be offered in two different barrel lengths, 500mm and 600mm. The 500mm will feature the Superior Liner (except the .35 caliber). The 600mm will feature the Superior Heavy Liner across all caliber options.
