GEN 8 m4 bullpup
thingiverse
This is my bullpup m4 conversion designed to fit the standard gen 8 gelball blaster receiver. it requires only small modifications to the receiver to fit though a longer front guard such as i did is suggested. You will need m3 and m4 screws and nuts in various sizes, a small compression spring is needed for the trigger, a pair of small magnets 5mm diameter 2mm wide and a micro switch with a longer arm on it such as this one https://www.jaycar.com.au/spdt-250v-3a-miniature-micro-switch-with-lever/p/SM1038
