This all-in-one air rifle has been engineered to satisfy the most demanding airgun shooter with high-performance features. The Impact is completely adjustable: air valve control, hammer spring tension, and even regular adjustments can be made externally to allow for various shooting scenarios. The Impact now incorporates the new FX Smooth Twist X Barrel which is a fully rifled barrel liner. FX’s proprietary process of imparting the inner rifling of the barrel from the outside of the steel tubing, is an outstanding upgrade in airgun accuracy. This Smooth Twist X Barrel is housed in the Interchangeable Barrel Liner System allowing the shooter to swap and change barrel liners of various twist rates, bore specifications and more; all to tailor the barrel to different projectile sizes. The breech and barrel assembly also incorporate a quick-change system that allows for any of the four calibers (.177, .22, .25 or .30) to be used. All that is required is an extra barrel and pellet probe for each caliber. Other notable features of this bullpup include a unique match grade trigger system that does not rely on connection rods or linkages. The smooth side cocking lever is placed perfectly above the trigger to allow for the quickest possible follow-up shot. This high powered and tactical, yet lightweight and compact airgun is a sensational piece of cutting-edge technology. With all these features wrapped into one rifle, the FX Impact will continue to be the benchmark for air rifles worldwide.
