THIS IS FOR AIRSOFT ONLY

This is a conversion kit for a We Tech GBB M4 airsoft gun. I have included profiles for all BL printers, but I only have an X1, so please feel free to create new profiles. The assembly instructions include the parts list for non-printed parts. To make the charging handle function, you must remove the plastic/rubber plug from the front of it by punching out the pin from the top side.
