Appearance alone isn't sufficient proof that the Classic Green is a variant of the SG 550 since the Classic Green could have initially evolved from the SG 540 and then encorporated some of the characteristics of the SG 550 --- only SAN can really prove the later, though.
This is also my belief since they let the FAMAE in as well which is based off the 540, so if the gun is a mishmash of a 540 based receiver and 550 "components", is it not therefore a 540? Like the FAMAE?
