Hardware Kit for MK VII Series (Self-Print)

All the parts you can't print for a self-printed G3D drum magazine of the MK VII series: the winding spring plus all required screws and nuts. Printed parts are not included.

Which version do I need?

• VII-S: for the compact MK VII-S.
• VII FST & RB – single winding spring: for the FST MK VII 66 with the standard winding wheel.
• VII FST & RB – dual winding spring: for the FST MK VII 90 +RB with the dual winding wheel – more spring capacity, so you wind less often.
