The FX Impact M4 Standard PCP Air Rifle in .22 caliber with a 600mm barrel represents the high-end pinnacle of modular pre-charged pneumatic design. It balances structural rigidity, a high shot capacity, and endless tuning flexibility for both pellets and slugs. 
Core Specifications
  • Barrel: 600mm (23.62”) Superior STX Barrel System.
  • Overall Length: 860mm (34”).
  • Weight: 6.85 lbs.
  • Air Capacity: 480cc removable carbon fiber cylinder (some regional configurations utilize a 300cc cylinder).
  • Plenum Volume: 75cc Power Plenum 750.
  • Max Fill Pressure: 250 BAR (3,625 PSI).
  • Shot Capacity: Up to 270–330 shots per fill in .22 caliber.
  • Magazine Capacity: Redesigned high-capacity 34-round wheel optimized for long slugs. 
Key M4 Generation Upgrades
  • AMP MKII Brass Piston Regulator: Stronger single-regulator setup featuring faster refresh rates, handling up to a 170 BAR working pressure. 
  • Rigid Top Plate & Rail: A significantly thicker top plate reduces flex across the backbone, incorporating a machined dovetail to mount an adjustable 30 MOA Picatinny scope rail. 
  • Quick Set Trigger (QST): A completely redesigned target match-grade trigger unit offering unmatched adjustments. 
  • Dual Transfer Ports: Specifically engineered with optimized internal geometry—one side tuned for standard pellets, the other flipped for high-velocity slugs.
Factory Tuning & Projectile Tips
  • Pellets: Easily pushes standard 18.1 grain and heavier 25.4 grain pellets past 890–950 FPS using the tool-free macro and micro hammer wheels. 
  • Slugs: The standard Superior STX liner excels with light-to-medium slugs (up to ~25–30 grains). For heavier, high-BC hunting slugs exceeding 33 grains, upgrading to a 600mm Superior Heavy Slug Liner and installing the FX Slug Power Kit (tungsten hammer weight and high-flow probe) maximizes stability and muzzle energy.
