   Used to get Toolcrafts for this price but in this climate I’m going hmmmmmmmm at $55.

   Wish we knew more about who makes this. It says anodized blue for finish and blue steel material, a little odd

5. darkcity9620 – October 18, 2021

   OOS and now the price says $89.99. I know I don’t need it, but I want it! And I want even more now that it’s sold out. I hate and love this sub at the same time! Guess I’ll go find something else to spend that money on…

   In for 2 here as well.

   I was choking on how much any of the big names want for a BCG, this will work just fine for a plinker.

    Both of mine arrived today. They look fine. However the bolt is not marked like other MPI bolts are.
