VFC SCAR-H GBB - replacement internals?

[Malthus101]

Hi

Anyone know of replacement internal parts for the VFC SCAR-H GBB?

These parts seem to exist for the WE version but not for the VFC version.

I'm talking reinforced nozzle/bolt/bolt carrier, basically all the parts that would also need upgrading (I'm not a tech with airsoft)

Thanks
