its a karni reg.
its been swapped with red parts from another cocker.
the worrframe wasnt out in 2k3 either.
after pausing the video it looks like it has an mp4 ram (i think) and tickler lpr, also off a karnivor. its a parts build, only thing stock is probably the body and internals. i cant tell what jewel that is by the video...wgp did have a couple different ones. it wouldnt say FUKU though.
this is a stock 2k3:
