FX Impact M4 – The Next Generation of Precision Airgun

The FX Impact M4 represents the evolution of one of the most iconic PCP airguns ever created. Since its first release in 2015, the Impact has redefined modern airgun performance, and the M4 version takes that legacy to an even higher level. Built for accuracy, strength, and versatility, the Impact M4 is designed to deliver unmatched consistency for both professional shooters and hobbyists.

At its core, the Impact M4 introduces the revolutionary FX Quick Set Trigger (QST) a fully adjustable system that allows shooters to instantly switch between hunting, standard, or match-grade trigger settings with just a single screw adjustment. This means you can customize your trigger feel without replacing components, ensuring perfect control for every shooting discipline.

To enhance precision and durability, FX has reinforced the rifle’s structure with a thicker and stronger top plate, providing greater rigidity and stability for optics mounting. The new FX Grip has been ergonomically redesigned with improved palm support and a beavertail contour, giving shooters a secure and comfortable hold for better accuracy during long sessions.

Powering the Impact M4 is the upgraded brass piston AMP MkII regulator, known for its faster refresh rate, improved consistency, and ability to handle higher bottle pressures up to 170 bar. This ensures every shot is smooth, stable, and powerful. The M4 also features redesigned high-capacity magazines, made from reinforced materials to handle even the heaviest slugs with ease.

The extended scope rail now combines dovetail and Picatinny systems, offering more flexibility and a perfect alignment for your optics. The airgun also includes a built-in shroud system with an optional moderator, providing quieter shooting while maintaining top-tier accuracy.

Designed with both right- and left-handed shooters in mind, the sidelever cocking system is smooth, reliable, and ambidextrous. Dual WIKA pressure gauges allow precise monitoring of both regulator and airtube pressure, ensuring optimal performance every time.

The FX Impact M4 remains true to its signature look while incorporating subtle design refinements for better balance and function. It’s compact, powerful, and extremely adaptable ideal for benchrest, target shooting, or precision training.
