Im not too familiar with the fathers of freedom version of the MB bcg’s but the following two are HPT, MPI, and have upgraded internals for way less than $180.
MicroBest Phosphate+ BCG (has sprinco springs & OKS screws) ($92) or
MicroBest Premium All Chrome BCG (has sprinco springs and OKS screws) ($120)
The extra jump from ~$100 to $180 is mostly for the name/branding/marketing costs for the name brands. As
@Cascade Hemi has pointed out I highly doubt these companies are doing that much extra stuff to these bcg’s to justify nearly doubling the OEM price
