Description
MP7 GBB part MGG1-19 for Tokyo Marui. Better to print with ASA or Nylon because of high impact load of spring. PETG also allowed, but high risk of cracking after first usage.
Project file also included body pin.
P.S. if this part anywhere being cracked, it will be still working until disassembled.
