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

Part of the FX Impact Slug Power Kit is a 5.5 mm (.22) pellet probe thats adjustable in length by means of an Allen screw at the rear. With included bushes thatll slide on with an interference fit, the probe is also suitable for the calibre 6.35 mm (.25). 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 hammer spacer thatll add extra weight to the hammer while also increasing the preload on the spring. Theres also a buffer to protect the valve against the increased impact.

The extra speed that can be maintained is:

• 5.5 mm (.22) between 35 and 55 fps
• 6.35 mm (.25) between 50 and 80 fps
• 7.62 mm (.30) between 30 and 60 fps
