Good point, but isn't it easier to say that than,
Just sayin'. I'd think you'd want to run an H2 because it'd probably be more optimal in an Suppressed SBR, I saw this referenced in another thread, but grant seemed to have a similar setup.
After reading this thread, Dunno what to think

It appears most SBR's suppressed will be overgassed, it might be ideal to try an H2 or H3 as the bolt velocity is rapidly increased.
Food for thought, I might use that for reference or shoot Grant a PM.
Grant's awesome as a side note, I use the guy whenever I can, extremely inclined on the knowledge of the weapons he sells, great prices, quick responses, good service.
I'm thinking it'd be worth it to try an H2 if a regular Suppressed SBR will shoot 5.56mm fine suppressed with an H3.
Food for thought.
