Black Creek lowers?

[~kev~]

I used the search feature before posting, nothing to answer my question came up.

How good are Black Creek lowers as compared to PSA or Spikes lowers?

I did several google searches and just about everything that came back was about 9mm lowers. I know multi-caliber will do both.

This is for a basic plain Jane build, nothing special, just for use around the farm. Will probably use a PSA or CMMG lower parts kit. I just want a basic lower to slap a PSA upper on.

So, how does Black Creek rank?
