This is an outer barrel (adapter) for airsoft rifles (AEGs). It fits perfectly on the hopup chamber, the inner barrel and the outer retaining screw. It has 14mm CCW thread for silencer (suppressor).
The replica it was used on is a CYMA CM.513. I believe it fits many other replicas with the same mounting style.
Total length: 89mm
The idea behind that came when I decided to make a really short version of my M4 (PDW).
My suggestion is to be printed with supports and with the thread facing up.
For airsoft use only!
Important: set support overhang angle to 60, otherwise you will end up with non-removable supports.
