The FX Impact M4 is the latest iteration in the hugely successful Impact series, pushing precision and shooting capability in the airgun industry.
This airgun is available in two distinct colours – the original all-black version or the bronze version to give it just that little extra. As well as this, the gun is available in multiple configurations, including a compact and standard version, sniper, or extended for every use.
The Impact has a new design throughout without deviating too far from the M3. This has allowed improvements in all areas without changing the overall aesthetics or feel of the system.
The FX Impact M4 has a completely redesigned high-capacity magazine which are now made from much stronger materials and include a new internal mechanism to ensure the inner drum will rotate smoother even when loading the heaviest slugs available on the market. The Impact M4 also now comes standard with a new brass piston regulator that is stronger and has faster refresh rates. A far more consistent and easily handled higher bottle pressures with a max pressure of 170bar.
To further enhance the performance and shooting experience, FX have improved the overall rigidity of the Impact M4 by designing a new top plate that is much stronger and thicker which brings more strength and rigidity throughout the entire platform. The new QS trigger unit and top rail introduced have increased the comfort of shooting the Impact, as well as the all new FX grip that is more defined and comfortable to grip to.
The first major upgrade to the Impact M4 is a completely new trigger system. The FX quick set trigger has been adjusted to allow the user to change from standard, hunter, or match-grade, all with the change of one screw.
