GRS Laminate Stock — Norwegian Ergonomics at Its Finest
The GRS stock stands out as one of the FX King’s most impressive features. Norwegian firm GRS built their reputation on ergonomic and multi-adjustable laminated stocks. These laminated stocks resist slight warping better than normal wooden stocks under temperature and humidity changes. Consequently, this design enhances accuracy. You can adjust both the cheekpiece and the butt stock in fine steps without tools. Two easy-to-operate push buttons are integrated into the stock design. Finger grooves and a slight angle make this the most ergonomic FX stock to date. The FX King 600 GRS Green Mountain is available with a right-handed stock only.
Engineering Excellence — Dynamic Block and Quick Tune System
The FX King showcases exceptional engineering. The design facilitates optimal airflow through meticulous engineering. The Dynamic Block with a balanced valve ensures flow of precisely set air volume, achieving high performance with minimal deviations. The block can accommodate projectiles up to 13mm in length. The Quick Tune System features macro and micro hammer spring preload adjustments with a clear scale for precise setting selection. The AMP MKII regulator is externally adjustable, allowing fine-tuning of pressure to match specific ammunition for optimal consistency. The rifle also features a High Power/Short Impulse one-piece valve for significant and rapid airflow.
Superior STX Barrel System and Accessories
The renowned Superior STX barrel system includes a changeable Superior STX Heavy liner. The manufacturing process uses externally pressed rifling. This meticulous design ensures a smooth interior barrel surface and perfect sealing around the projectile. The barrel shroud serves three functions: it reinforces the barrel, acts as an integrated sound moderator, and houses the 156cc Power Plenum. The 9MIL/30MOA Picatinny rail expands the adjustment range of your riflescope for long-distance shots. Two Weaver/Picatinny accessory rails on the sides accept bipods, lights, or other accessories. The adjustable 2-stage match trigger offers angle, distance, and height adjustments for the blade.
