With the FX Impact Slug Power kit you’ll be able to get just that extra bit of precision and speed out of your FX Impact air rifle.

Part of this kit is a 5.5 mm (.22) pellet probe that’s adjustable in length by means of an allen screw at the rear. With included bushings that’ll slide on with an interference fit, the probe is also suitable for the calibres 6.35 mm (.25) and 7.62 mm (.30). The seating position, i.e. how far the slugs are pushed into the barrel, influences the accuracy and this adjustable pellet probe provides you with the means to experiment with that. An important feature, as you can fine tune on one specific slug.

Other parts in the FX Impact Slug Power kit that mainly influence the speed are a lighter valve return spring that lets the valve stay open longer and a tungsten hammer that’ll add extra weight while also increasing the preload on the spring. There’s also a buffer to protect the valve against the increased impact. 

All parts are machined with very tight tolerances and the set is suitable for use in all types of the FX Impact.
