the lighting is a stand 2k spec cocker, the superbolt is too its just a mini.
the only difference is the grip frame screws are 8/32" compared to 10/32". its something dye does on their guns, and these are knock-offs of the dye cockers.
feednecks are held in by a set screw.
stukam you are probably thinking of the trilogies on the valve part, they use an 11/16" cocker valve like a merlin and a standard hammer spring, but a spider valve spring.
