Mantis Tactical Slingshot Ergonomic Grip

This is a brand-new slingshot launcher created by combining the best features and improving on shortcomings. It incorporates an ergonomic grip for a more comfortable feel. The rail length has been increased for overall proportional coordination, extending the rubber band's stretching distance. The bow arms have been designed with superior strength and structure, resembling a praying mantis's face when viewed vertically, hence the name "Mantis". In short, after optimizing multiple versions, the overall design has achieved the desired effect, and it is now shared with everyone. Feel free to download.

There are two versions in the file: a precision 8mm ball version and an 8mm magnetic mud ball version (actual aperture is 9.1mm). You can choose according to your needs.
