I think a couple of the sponsors sell Tactical Solutions parts (or is that Tactical Innovations?)... You may try Wolverine, Questar, or Wanstalls. I think I may have seen some on the EE as well (from a sponsor)... You could try a search there.
However, Dlask also makes compensators... You could always take a look on their site and see what they have, or send them an email. It won't be TacSol, but they might pique your interest, and they're made in Canada (so no issues regarding importation, wait times, or anything).
