When will PSA have Nickel Boron AR10 BCG's again?

Sometimes it seems like my target shooting is an endurance competition,
pitting a 2016 PSA upper against a near identical 2019 PSA upper.

Anyway I need to get another 308 BCG.

Any chance of buying a Nickel Boron 308 BCG for $150 ?

Unfortunately I do not have an eta for more NIB 308 BCG’s at the moment.
