FX Impact M4

The FX Impact M4 is the fourth generation of the FX Impact series - arguably the most successful all-rounder PCP series ever. Modular, multi-adjustable and ultra-accurate - suitable for virtually any shooting discipline there is! From the competitive benchrest shooter to the hunter and even the collector - There is nothing the Impact M4 won't conquer.

Compared to the Impact M3 before it, FX made some radical (and some more subtle) changes, bringing the FX Impact M4 to yet a higher level, while also improving usability. Here is some of the more important features and changes:

AMP MKIll regulator

The Dual Regulator system has made room for a single AMP MKIll regulator with a brass piston.

With that, it's stronger and more consistent, with a higher refill flow thrown in too. Besides that, this single regulator is more than capable of withstanding high working pressures up to an impressive 170 bar (2500 psi). Note that working pressure is something different than filling pressure, with the latter being 250 bar (3600 psi). You can adjust the regulator with a screw, at the rear of the trigger, inside the trigger guard.

Top plate with dovetail

The FX Impact M4 Sniper has a revisited top plate. The plate is thicker, which gives more rigidity to the whole air rifle, and it now features a dovetail rail that allows you to slide the 30 MOA Picatinny rail exactly there where you want it. That Picatinny rail has become slightly longer too, giving you even more freedom in mounting. The forward tilt of the rail with 30 MOA, will offer you a broader adjustment range on the rifle scope if used on long distances.

Quick Set Trigger

In every aspect, the complete trigger unit is new. Because the FX Impact M4 is such a universal platform, FX looked at what was needed to make the trigger adjustable and refined in such a way, that it would suit all types of shooting. When hunting, you'd like a predictable long stage while in sport shooting, you'll prefer a featherweight trigger with a refined glass-like breaking point. With the Quick Set Trigger, all it takes to change between these two is to adjust a single screw. Besides that, you can reposition the whole trigger unit, setting it further or closer. And both stages are adjustable, while the trigger blade is adjustable in height and rotation.

Power Plenum 750

With a regulated 75 cc air buffer, the FX Impact M4 Sniper has plenty of air at the ready behind the valve to deliver plenty of power. Enough to give even the heaviest slugs the perfect velocity. 

The large capacity of the plenum also allows for a lower regulator pressure than would be the case with a smaller plenum.

Adjustment options

Part of why the FX Impact is so popular, is that it is adjustable on so many levels. So it comes as no surprise that you can finetune the FX Impact M4 Sniper left, right and center. We've already pointed out the adjustable regulator, but that's not the extend of this rifle's adjustability by far.

With the power knob on the front, just above the air reservoir inlet, you can adjust the preload of the valve spring. When you turn it anti-clockwise, indication rings appear. The more rings you see, the more air will be let through.

On the left side of the system, the hammer spring preload is adjustable with the famed Quick Tune system. With this, you can adjust the preload with a macro-adjustment wheel in 16 big steps (5-15 fps or 1.5-4.5 m/s). Thereafter, you can do some finetuning with the micro-adjustment wheel ((1-2 fps or 0.3-0.6 m/s). The more preload, the more air will be let through and the faster the rifle will propel the projectile.

And then there's the Dual Hole transfer port in the barrel that's a feature on most calibres. It means that the barrel sports two openings on opposite sides where air is let through. The small opening, marked with a 'P', is perfect for use with pellets. By twisting the barrel 180 degrees, a larger opening will be situated in front of the transfer port, allowing for more airflow (thus more power) for heavier projectiles, such as slugs. That's why they indicated it with an 'S'.

Superior STX barrel

FX uses liners inside its barrels, with the rifling pressed-in from the outside. This gives a very smooth inner surface with minimal friction. As an added advantage, you can quickly change the liners for another calibre or type of ammunition. The only thing you need to change too, is the pellet probe. On this Slug Ready version, we already installed a Superior Heavy Barrel and Slug Power kit.

Adjustable shoulder piece

The buttstock of the FX Impact M4 Sniper is adjustable in height. You can do this stepless by loosening a screw on the right side. That way, you can obtain the perfect shooting stance for all postures. The buttstock has a comfortable concave shape with plenty of grip.

UGl grip

For next-level comfort of and feel, FX Airguns equipped the FX Impact M4 with a new AR15-style UGl grip with a more defined ergonomic shape and also contact areas with plenty of grip.

High-capacity magazine

FX even renewed the magazine with new, stronger materials for durability. They optimised the internal mechanism so the rotating centre will turn smoothly and firmly with even the heaviest slugs loaded

Accessory rails

Besides the dovetail mounted 30 MOA Picatinny rail, the FX Impact M4 Sniper now also features two Picatinny accessory rails on the sides. There's also a Picatinny rail at the underside, placed perfectly for mounting a bipod.

Two-sided cocking lever

The cocking lever features a comfortable big knob and you can find it on the right side of the FX

Impact M4. However, you can easily reverse the lever to the other side for those who prefer the lever on the left side of the PCP air rifle.
