FX Impact M4 Compact .22 Black

FX Impact M4 Compact — .22 Caliber PCP Air Rifle — Black

All the Impact performance, none of the bulk.

The FX Impact M4 Compact in .22 caliber brings the legendary Impact platform into a shorter, lighter package — ideal for shooters who want serious PCP performance without the length and weight of the Standard or Sniper configurations. With a 500mm barrel and a 300cc carbon fiber bottle, it's built for maneuverability in tight hunting spots, blinds, or anywhere a shorter rifle makes the difference.

Why Shooters Choose the Impact M4 Compact

• Same platform, smaller footprint. You get the Impact's core engineering — Quick Set Trigger, AMP MKII regulator, Power Block — in a rifle that's easier to carry and maneuver.
• Built for close-quarters hunting. The shorter 500mm barrel and lighter overall weight make it a natural fit for blinds, dense brush, or any situation where a long rifle is a liability.
• Strong shot count for its size. Around 110 shots per fill in .22 means the Compact still delivers solid range time despite the smaller 300cc bottle.
• Fully tunable. Adjustable power, trigger, and regulator settings let you dial the rifle in for pest control one day and small-game hunting the next.
• Proven reliability. Owners consistently report extreme accuracy and rock-solid build quality, with the rifle holding tight groups well out to 50 yards.
