FX Impact M4 — Extended — .22 Caliber PCP Air Rifle
The most iconic name in airguns, pushed to its furthest reach.
The FX Impact M4 Extended in .22 caliber is the longest-barreled configuration of FX's flagship Impact platform — the rifle that changed the airgun industry when it first launched in 2015, now in its most refined and rigid form yet. With an 800mm barrel and the largest air capacity in the M4 lineup, the Extended is built for shooters who want maximum shot count and peak velocity consistency in one package, whether on the bench, in the field, or on the competition line.

Why Shooters Choose the Impact M4 Extended
The benchmark platform, maximized. The Impact name carries a decade-plus reputation for accuracy and innovation — the Extended config pushes that platform's barrel length and air capacity to their practical limit.
Shots for days. Up to 330 shots per fill in .22 means fewer trips back to the compressor and more time shooting.
Pellets or slugs, dialed in. The dual transfer port and Quick Tune system let you optimize the same rifle for either projectile type without major surgery.
True ambidextrous capability. Both the bolt and magazine can be moved to the left side, giving left-handed shooters the same ergonomics as right-handed ones.
Built to compete. A thicker, more rigid top plate and adjustable scope rail positioning mean your optic stays put and your eye relief stays exactly where you set it.
Backed properly. FX's 3-year transferable warranty reflects genuine confidence in the build.
