Scope not included
The FX Impact M4 is now available in a .20 calibre, sub‑12 ft/lbs configuration, making it perfectly suited for UK airgun shooters who want premium performance within legal power limits.
The latest Impact MKIV introduces a range of refined design features that make adjustments quicker and more accessible in the field. Fitted with the advanced FX UG1 grip, the rifle provides excellent ergonomics, improved control, and outstanding shooting comfort ideal for precise target shooting and pest control.
A new adjustable 30 MOA top rail allows shooters to position their scope exactly where they need it. The rail slides along the receiver to achieve optimal eye relief and alignment, helping you get the most from your optic. The upgraded top plate is stronger and more rigid, improving overall durability and maintaining zero even with heavy use.
For shooters who like to customise their setup, the side-mounted accessory rail offers convenient mounting options for accessories such as torches or bipods. The rifle retains the smooth, ambidextrous side‑lever action that the Impact series is known for, delivering fast and reliable cycling whether you’re left‑ or right‑handed.
The quick‑set trigger system allows for fast and precise trigger adjustments, helping shooters fine‑tune the feel to suit their preference. The rifle also features a high‑capacity magazine design, providing reliable feeding and a generous shot count from the regulated air system.
Further trigger adjustments are made simple thanks to the slotted trigger guard, which gives easy access for fine tuning without dismantling the rifle. Comfort is enhanced by the fully adjustable buttstock, allowing shooters to tailor length of pull and fit for improved stability and control.
With numerous internal refinements and the renowned FX engineering, the FX Impact M4 .20 calibre (sub‑12 ft/lbs) delivers exceptional accuracy, consistency, and versatility for UK airgun shooters.
