The FX Impact M4 (MKIV) represents the next evolution in precision air rifles, packed with advanced features for serious shooters. Designed for performance and adaptability, the MKIV offers improved ergonomics, durability, and ease of adjustment.
Featuring the all-new FX UG1 grip, the Impact M4 delivers enhanced control and shooting comfort. Its redesigned adjustable 30 MOA top rail allows for seamless scope alignment by sliding along the receiver rail—ensuring perfect eye positioning and accuracy. A stronger, more rigid top plate further enhances stability and reliability.
The rifle retains FX’s ambidextrous smooth side lever, known for its dependable cycling, while introducing a side-mounted accessory rail for expanded customization options.
A major upgrade is the quick-set trigger system, allowing precise, on-the-fly adjustments. The redesigned high-capacity magazine not only increases shot count but also boosts feeding reliability—ideal for extended sessions.
Further refinements include a slotted trigger guard for easy trigger adjustment access and an adjustable buttstock for a personalized shooting fit. Internally, the M4 features performance-enhancing upgrades that improve efficiency and consistency across the board.
Whether you're targeting precision or customization, the FX Impact M4 is built to deliver elite-level performance straight out of the box.
