Next piece is a new greeblie on the backside of this blaster that to my knowledge has not been seen yet and surprised me when I saw it. Again this looks to have been added on after the movie as I havenÂ’t seen this anywhere else as of yet. So it looks to be so blue plastic part with a knurled wheel on the inside of the one end. This could be anything from a toy noisemaker or anything picked up out of a scrap junk box. Also the pics are reversed, as these are shoots taken with the mirror backing of the backside of the blaster. Oh and it sits on the scope rail of the ejector port side, right between the scope rings.
