M249 crane stock adapter

STL FILES can be found here: https://www.prusaprinters.org/prints/137894-m249-crane-stock-adapter-airsoft

This is an adapter to fit a crane stock on an airsoft M249

Compatibility: tested to fit on my Classic Army M249, which should mean that it will fit the A&K M249 as well. According to the comments, this is also confirmed to fit on a G&P M249.

Hardware:

• Buffer tube (I used a Specna Arms variant) with the included M5 screw
• M5 nut

Printing instructions:

I believe the strongest print orientation is to print the adapter on its side (as shown in the first picture). Use supports and PLENTY of walls.

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.
