[Hectic]

ya no worries seems like it should be an easy mod if the person there was right. I know i read someplace else about the star one being like 10mm too long in the rail, or somethin like that. So i bet even that could be fixed to fit u would just have some rail sticking out in front of the launcher, i think i also read that the dboys is a vfv clone so that would be y its only off by a lil bit, again tho i was just skimming through stuff so i could have it all mixed up lol but the person i quoated seems to have tested it out so its likely a reliable answer.
not sure if your friend has a scar L or H or even if dboys makes both or if that even makes a difference so u may want to dbl check on that but otherwise it seems like that is the option.
