Description
FX Impact M4 PCP Air Rifle
The FX Airguns Impact M4 is the latest evolution in the renowned Impact series, delivering exceptional precision, power, and adjustability for serious airgun shooters. Designed to push performance even further, the Impact M4 refines the proven M3 platform while introducing key upgrades that enhance consistency, reliability, and user control.
Available in multiple configurations, including compact, standard, sniper, and extended versions, the FX Impact M4 can be tailored to suit hunting, target shooting, or long-range precision work. It is also offered in classic all-black or striking bronze finishes, allowing shooters to choose a style that matches their preference.
Enhanced Design & Rigidity
The Impact M4 features a redesigned top plate that is thicker and stronger, improving overall rigidity across the platform. This added strength enhances stability and accuracy, especially during high-power or long-range shooting sessions. Despite these structural upgrades, the rifle retains the familiar ergonomics and balance that Impact users appreciate.
In addition, the new FX UG1 AR15-style grip provides improved comfort and control, making the rifle easier to handle during extended use in the field or on the range.
Upgraded Magazine & Regulator System
One of the key improvements is the completely redesigned high-capacity magazine. Built from stronger materials, the new internal mechanism allows the drum to rotate more smoothly, even when using heavier slugs. As a result, feeding reliability and consistency are significantly improved.
The rifle also features a new brass piston AMP MKII regulator. This upgraded regulator delivers faster refresh rates and more stable air management, allowing the rifle to handle higher bottle pressures up to 170 bar with excellent shot-to-shot consistency.
Quick Set Trigger System
Another major enhancement is the all-new FX Quick Set Trigger. With a simple adjustment using one screw, shooters can quickly switch between standard, hunter, or match-grade trigger settings. This allows the rifle to be easily configured for different shooting styles and disciplines.
Combined with the reversible smooth sidelever cocking system, the Impact M4 offers smooth operation and a highly customisable shooting experience.
Built for Precision & Performance
The FX Superior STX 600mm barrel ensures outstanding accuracy and consistency across both .177 and .22 calibres. Paired with a 480cc air bottle and 250 bar fill pressure, the Impact M4 delivers impressive shot counts, making it ideal for long sessions without frequent refilling.
Overall, the FX Impact M4 PCP air rifle represents a new benchmark in high-performance airguns, combining advanced engineering, modular flexibility, and competition-level accuracy in one premium platform.
