The file 'M4 Stock Adapter For AK 3D Printer Model' is (stl) file type, size is 59.3KB.
My, Stock adapter for CYMA 028. You should be able to fit most of buffer tubes on it.
the fitment is really tight, so there should be no problem with loosing it on field.
if you have any questions or problems with it please let me know, I will be able to edit it really easly.
