Attention! The models are for left-handed people. But you can easily mirror them.
You still need an M6/15mm screw
4x m4/5mm grub screws
a steel or aluminum pipe diameter 10mm length 300mm
2 pieces neodymium magnet
I also made the shoulder rest out of aluminum (too much plastic otherwise :-)

I've been playing with this gunstock for 2 years and don't want to go without it anymore
