The special rubber bullet designed to our specifications is particularly suitable for those who want to have an effective non-lethal deterrent for housing defense. The particular flat-head shape with transverse grooves causes the section to widen on impact, preventing penetration, while the lower fins guarantee stability and precision. The Green (soft) version is indicated for use between 5 and 20 meters, while the Red (hard) version is more suitable for distances between 20 and 40 meters. The use in particular situations or at distances shorter than those indicated, can however cause serious damage to people, animals or things.
