New videos and reviews every day 6000+ reviews from our customers Swedish manufacturer FX Airguns introduces the fourth generation of one of the most successful PCP air rifles, called Impact M4. And it’s not just a simple upgrade – almost all external and internal components have been redesigned, while it still retains the characteristic style of the Impact series.
The main frame holding everything together has been reinforced for overall increased rigidity of the air rifle and is now equipped with a hidden 11 mm dovetail rail. This allows you to move the 22 mm Picatinny mounting rail forwards and backwards, giving you more freedom when installing a riflescope. The sliding rail features a 30 MOA cant, making it easier to zero your scope for long‑range shooting.
The entire trigger mechanism has also undergone major changes. Impact M4 features the so‑called “Quick Set Trigger” – a trigger that you can easily tailor to any purpose. Whether you are planning to go hunting with a heavier trigger pull, or to a shooting competition that requires maximum sensitivity, you can tune the rifle using a single screw in just a few seconds.
The externally adjustable AMP MkII pressure regulator with a brass piston has also been modernized; it is much more durable, more responsive, ensures even more consistent muzzle velocity and can handle a maximum regulated pressure of up to 170 bar.
The high‑capacity magazine has been redesigned as well and is now made of Polyoxymethylene (POM), and its new internal mechanism ensures smooth rotation even when using the heaviest available ammunition. The AR‑15 style grip is more robust and textured in the gripping areas for better shooting comfort.
Everything else remains unchanged. The shrouded barrel with externally pressed rifling is as perfectly accurate as ever, the rifle comes with a sound moderator with 1/2" UNF thread, the carbon bottle can be filled up to 250 bar, you will find two WIKA manometers on the rifle (one for the pressure in the bottle, the other for the regulator), there are 3 Picatinny rails located on the sides and under the barrel, the hammer spring preload can be adjusted using the micro and macro dials of the Quick Tune System, behind the regulator there is a large 75 cc power plenum, the sidelever can be swapped to the other side by removing just two screws, the safety is located on the right side, the buttpad is height‑adjustable, and the bottle is filled via a standard Foster quick coupler with 1/8" BSP thread.
