Maximize the power and accuracy potential of your FX Crown rifle, especially when using slugs, with this simple kit. It incorporates key modifications such as two hammer weight spacers placed in front of the return spring on the hammer weight guide. This allows for increased compression on the hammer spring and adds weight to the hammer, resulting in velocity increases. Working alongside this modification is a lighter valve return spring, which enables the valve to stay open slightly longer, allowing more air to propel heavier projectiles like airgun slugs. This kit is dedicated to FX Crown users.
