[MWR TMC] Mag Coupler
If you have a need to couple your mags and are okay with offseting them to access the winders without having to decouple your mags then this is a great option for you! It is a very simple and sleak design using a single M5 bolt to secure both mags together. No springs or quick release featured on this one, just straight up clamping. They are printed with 100% Infill for superior strength and reliability.
Parts come preassembled and include:
1x TMC mag coupler parts
1x M5 65mm stainless steel screw
1x M5 stainless steel nut
