Looking for fast reloads?
Slap a coupler on those mags!
Press-fit
semi-permanent addition
tight tolerances (0.15mm)
Available with windows or no windows:
Standard side by side couplers
Flip couplers (for bullpups) with always left or always right configurations.
No supports necessary.
Orient with middle coupler down.
Tolerances tight, use dry filament with dimensional accuracy of at least ±0.03 mm; you may need additional post processing to get your mags in and out otherwise.
Removal of these couplers will likely result in your magazine's baseplates coming off.
In my experience they have simply popped back in.
