The FX Dynamic is built around a robust aluminum receiver and M-LOK-style aluminum handguard with M-LOK slots along the bottom for secure mounting of compatible fore-end accessories. The rifle’s finish is black throughout, including the receiver and handguard, and it carries clear Swedish factory markings.
Its 500 mm shrouded barrel uses FX’s STX Superior (Smooth Twist X Superior) liner, and the shroud is capped with a knurled end cap. The top of the receiver features an integrated 30 MOA (marked 6 MIL / 30 MOA) Picatinny rail for solid optic mounting. The right-side sidelever provides fast, smooth cycling, and the manual safety is clearly marked Fire/Safe.
Air management is straightforward and highly visible. Dual FX/WIKA gauges show system and regulator pressures, and the receiver is marked for Max Pressure 250 bar and Regulator Pressure. Filling is accomplished via a stainless-steel male Foster-type QD fill port near the AMP regulator. The rear-mounted 480cc carbon-fiber bottle serves as the buttstock and is finished with an FX-branded buttplate.
Chambered in .30 caliber with a noted capacity of 13+1, this rifle includes one FX rotary magazine. The length of pull measures 15.0 inches. Its combination of STX Superior rifling, regulated PCP operation, and clear pressure readouts makes it a well-equipped .30-caliber platform from FX Airguns.
