He doesn't really need the ray gun though. His main schtick was his "touch of death" which made his victims feel intense cold, which can always be explained another way. But that said, his "ray gun" could easily be similar to the cosmic cube or the guns that Hydra were using in Captain America. They've already got all of that side set up with Marvel. Since DD occupies the same universe, they can always draw from that.
