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.
