M249 Para suppressor adapter

This is an to fit a suppressor on an airsoft M249 Para. On the stock setup the gas key prevents a suppressor from being mounted, so I designed this small barrel extension.

Compatibility: tested to fit on my Classic Army M249, which should mean that it will fit the A&K M249 as well. Threading is 14mm CCW on both ends.

Printing instructions:

Print with the largest flat side down at 0.1mm resolution (same orientation as the picture).

Printing threads isn't easy, you need a well calibrated printer and good cooling (or print multiple adapters at the same time). If it doesn't fit you may need to scale the print up or down by 1% or so.

No supports needed

I printed this in PA6+CF filament and it seems fine, but your mileage may vary and you are using this at your own risk.
