FX Impact Compact Mk4 (Black)
The FX Impact defines what a modern airgun can be. A rifle without limits. It is a once in a generation rifle. A rifle that advances and evolves to push the boundaries of what compressed air can achieve. The Impact M4 once again redefines this high standard with groundbreaking advancements, upgrades, and a sole unwavering focus on creating the most advanced, most accurate, and most capable airgun you’ll ever shoulder.
The improvement within the M4 start with its dual regulators. The 1st regulator pre-reduces the air pressure in preparation for the 2nd regulator. This provides less stress on the 2nd regulator and achieves a more constant output pressure with less standard deviations.
The FX Power Plenum 720 is the new energy source of the Impact M4. This larger diameter plenum and its 72cc volume of compressed air provides both the precise amount of air and the power needed to propel the projectile. This new plenum works in coordination with the M4’s porting and valving to deliver the best power and efficiency available.
One of the most substantial upgrades to the Impact M4 is the user interface to the rifle: The Quick Tune System. This essentially tool-free system encompasses everything a shooter could use to fine tune their rifle’s accuracy, allowing unlimited possibilities. Adjust the air pressure the rifle is using via the dual regulators, how long the valve stays open with the front valve adjuster, and now adjust the strength of the hammer with the completely redesigned micro and macro power adjustments. The Rear Macro Power Wheel is a 16-step power wheel that adjusts the strength of the hammer in increments of 5-15 FPS (depending on caliber and reg pressure). This works in conjunction with the Micro Fine Adjustment. This tunes the hammer strength in incredibly small increments of just 1-2 fps with each click of the barrel roller, all at your fingertips. The combination of these is unrivaled in the airgun world!
Other improvements are vast and include an ambidextrous short throw cocking lever with enlarged handle, dual transfer ports on most calibers, tightened barrel housing tolerances to provide a tighter fit and better accuracy to the rifle, tightened breech tolerances to house the Side-Shot Magazine, an updated trigger that provides a crisp second stage break while also allowing the trigger post to move forward or back, 20 MOA built into the scope rail, Dual Wika manometers, and an abundance of forthcoming optional accessories.
The FX Impact is firmly seen as the greatest airgun made. The proof is undeniable. Shooters flock to the FX Impact, competition lines are dominated with the presence of this rifle, and shooters continue to expand what an air rifle can do with one rifle; the FX Impact. Why? It performs, it delivers, and it continues to provide the foundation for innovation. The FX Impact M4 advances the claim: the FX Impact M4 is the most advanced, most exciting and most accurate air rifle available.
