With the FX Maverick or FX Wildcat MKIII Slug Power kit you can get just a bit extra out of your FX Maverick or FX Wildcat MKIII air rifle when you use slugs

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 bushes that’ll 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. The probe is not suitable for pellet use.
Another part in the FX Wildcat MKIII/Maverick Slug Power kit that influences the speed is a bigger hammer weight. Around 98 fps (30 m/s) extra speed can be obtained, and another improvement will be the extra accuracy, thanks to the adjustable seating position.
All parts are machined with very tight tolerances and the set is suitable for use in all types of the FX Maverick and FX Wildcat MKIII.

This is the newest version with the Tungsten hammer upgrade
