Setting out to develop a true hunting powerhouse, FX Airguns delivers the Impact M4.35 Caliber. Retaining all of the adjustability and desirable features of the existing platform and some big new improvements, the Impact M4 .35 Caliber brings power and precision together in a marriage made in airgun heaven! Thanks to the upgraded Power Plenum 720, the Impact now ventures into large game hunting territory with authority.The Impact M4.35 Caliber features an 800mm Smooth Twist X Heavybarrel liner, set up to deliver stunning performance with larger pellets. Sending pellets downrange at high speeds and generating over 156 FPE (with the FX Slug Power Kit) at the muzzle, the Impact M4is firmly a part of the medium and large game hunting conversation. Coming standard with a removable 580cc carbon fiber air cylinder capable of a stunning 45 shots per 250 BAR fill, shoot with confidence whether you’re in the field or in a benchrest competition. The premium side shot magazine holds 18 rounds in .35, so you always have lead on tap.Of course, the beauty of the Impact platform is the ability to change calibers and settings at will. The highly touted AMP MkII(Adjustable Match Precision) regulator, micro and macro external hammer spring adjustment, and external valve control adjustment are all at your fingertips on the Impact M4. And because the rifle utilizes the Smooth Twist X liner system, swapping calibers or liners is a breeze. The ergonomics are perfect for shooters of all shapes and sizes, and make the operation of the rifle seamless. And the quick set trigger ensures you have full control over each and every shot, to place them exactly where you desire.
The rear Power Block sets the Impact M4 apart in terms of power adjustability. The power plenum stages the power capabilities of the FX Impact, the rear block handles that transfer of power much like a car’s carburetor. FX has completely redesigned the rear block and the valve house which allows for better air flow, efficiency, and power potential.The Power Block will be especially useful for those who desire to shootheavy slugs. The pressure in the plenum canbetter translate to the pressure behind the slug upon firing, allowing higher speeds and power. Those shooting heavy slugs are encouraged to add the FX Impact Tungsten Hammer weight to also allow for higher working pressures.If you’ve been itching for a big bore that offers true precision without skimping on power, the FX Impact M4 .35 Caliber is the rifle you’ve been waiting for!
