Airsoft CMG / AEP Gearbox reference (MP7, MAC 10, Vz 61)

As far as I can tell this is accurate enough to be useful. The gun I used it in fit the gearbox very snugly, and aligned well with the barrel. .STEP included.

Also included is a model of the JG Vz.61 barrel and chamber. Hopefully I will have the opportunity to model an MP7 and MAC 10 hop chamber eventually.

For mounting, I recommend supporting the gearbox under and behind the ledge at the back, and under and in front of the motor housing at the front. Press down from the top, in my case applied pressure using foam. Leave gaps on the sides with small supporting studs spaced evenly enough to allow the motor and spring housing to escape.

This for a TOY.
