"August 30, 2015 -- A note to our visitors and our devoted customers, the time has come and Blackrock Reef will be taking an indefinite hiatus from producing Mag-Racks. For those who are interested, we have no intentions to discontinue the MR3 product series, we are just unable to fulfill future orders.

This doesn't mean we won't be back in the future."
