SBR Flash / Blast

52 recommended the 5, earlier in this thread, but that may have been before he had some time with the 7. I think I read another thread where he thought the 30 cal suppressor would do better in a gas gun as it reduces some of the back pressure / port noise. I'm leaning towards a 30 cal Ultra 7, but I want to read some more to make sure I have a clearer understanding of the pros, cons, and variables.
