MP5 Mag Coupler

The original file for this was designed for airsoft mags.

I made some dimensional adjustments to get it fit on metal mags (KCI Gen 2 in this case). I intend to test it on ETS polymer mags. I do not expect it will work on windowed AC Unity mags as they have a larger profile.

I adapted it for M6 bolts and nuts because that's what I had on hand. I also re-arranged how the screws hold the two pieces together because the single connection point in the center of the original design put too much stress on the "wings" that hold the mags together and started to break when tightened down.


Hardware:
M6x30 bolts - 3
M6 nuts - 3
