Here is a set of interesting internals that came in a parts lot recently. I had assumed the bolt was from a Skirmish because the hammer catch slow was obviously different from a Phantoms.
Upon closer inspection they are clearly CCI Phantom internals though. I would guess the manufacturer was likely Hypertech but I haven’t seen any proof in ads that this is accurate so it’s just my guess.
These internals are pre TPC (tuned port compensator) and feature a very odd linkage rod
to connect the hammer to the bolt and prevent anti kinking.
They are stamped on the back of the hammer with “HB201” and “Patent Pending.”
These are chrome or nickel plated steel, and the connecting rod looks to be a lower grade then the rest of the internal set.
These internals likely date to 1989-1991.
