With the FX IMPACT SLUGS POWER KIT you’ll be able to get just that extra bit of precision and speed.
Pellet probe that’s adjustable in length by means of an allen screw at the rear. With included bushes that’ll slide on with an interference fit, and the important feature, you can fine-tune 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 that’ll add extra weight to the hammer while also increasing the preload on the spring. There’s also a buffer to protect the valve against the increased impact.
