The FX Impact is undeniably one of the most iconic airguns on the market, having changed the airgun industry forever & truly making an impact when it was released in 2015. With every new release of the FX Impact, it has been made better, more reliable, & accurate, reinforcing its presence in the industry. 

The FX Impact is an airgun that has proven itself to be suited for just about any discipline – whether you're a professional benchrest shooter, hunter, or a regular all-around shooter. The platform offers the perfect setup for every occasion. The new Impact M4 improves the platform in different areas while maintaining its iconic look that makes the Impact so recognisable out in the field & in competitions. 

The FX Impact has taken multiple first places and countless podium spots at all the major competitions around the world since its release. So, FX Airguns have made it their mission to make the FX Impact M4 not only better in many different ways but also stronger & more ridged so you as a shooter can keep competing at the top & fighting for those wins!

FX Magazine 
The FX Impact M4 has redesigned high-capacity magazines. The new magazines are made from a different, stronger material & have a new internal mechanism to ensure the inner drum rotates smoothly – even when fully loaded with some of the heaviest slugs on the market.

FX AMP MKII
The Impact M4 now comes standard with a new brass piston regulator that is stronger, has faster refresh rates, is more consistent & can easily handle the higher bottle pressures with a max working pressure of 170bar.

FX Rigid Top Plate
To further enhance performance & shooting experience, the overall rigidity of the FX Impact M4 has been improved by designing a new top plate that is much thicker & stronger, bringing more rigidity throughout the entire platform.

FX Scope Rail 
The new top plate features a dovetail rail machined onto it, enhancing strength while bringing more flexibility for mounting optics. The new scope rail is longer than before, & can slide along the rail so you get that perfect mounting position. It can also be tightly secured with the perfect alignment for the overall system!

FX Quick Set Trigger
The first major upgrade to the FX Impact M4 is an entirely new trigger system: the FX QUICK SET TRIGGER! The trigger offers true versatility – change from Hunter style with just the right amount of pull, to a standard FX trigger, or even a pure match grade trigger that is light, clean, & super crisp. All of this is possible with just a simple adjustment of one screw, eliminating the need to upgrade to a different trigger system.

FX UG1 Grip
With a new-style FX Grip that is more defined, & more comfortable to grip onto, with just the right amount of palm swell & a beaver tail to enhance the shooting comfort, giving you a firm grip on your Impact M4. This improvement enhances the overall feel and comfort of shooting the Impact M4.

FX Design Elements
The FX Impact M4 has a slightly new design – without going too far from its iconic look. Important improvements throughout the platform such as subtle new lines, cutouts for easy access to some parts, & angles to tie it all together make the FX Impact M4 even more practical & pleasing to the eye.

FX AMP MKII
The Impact M4 now comes standard with a new brass piston regulator that is stronger, has faster refresh rates, is more consistent & can easily handle the higher bottle pressures with a max working pressure of 170bar.
