New videos and reviews every day 6000+ reviews from our customers The Slug Power Kit allows you to get even greater accuracy and muzzle velocity from your FX Impact PCP air rifle.
This set includes a loading probe in 5.5 mm calibre, whose length can be adjusted using an Allen key. Thanks to the supplied adapters, this probe is also suitable for 6.35 mm calibre. For 7.62 mm calibre it is necessary to use the original loading probe.
The position of the probe determines how far the slug is pushed into the barrel, which has a significant effect on accuracy. This kit therefore allows you to fine-tune your rifle so that it exactly matches the specifications of your chosen ammunition. The lighter cylinder spring has a positive effect on the overall muzzle velocity of each shot.
All parts are manufactured using highly precise methods with very tight tolerances. The set is suitable for all versions of the FX Impact.
• Calibre 5.5 mm – between 35 and 55 fps (10 - 17 m/s)
• Calibre 6.35 mm – between 50 and 80 fps (15 - 24 m/s)
• Calibre 7.62 mm – between 30 and 60 fps (9 - 18 m/s) – Original loading probe must be used
