So I've noticed, looking at peoples' tests, that Disruptive's porting is one of the quietest portings out there. I'm pretty sure it's because of the stepped porting they have, but why is that? Shaft 4 barrels are pretty much the same, only they have twice the amount of holes for porting, and they lack the stepped porting and aren't nearly as quiet. Can anyone give me a reason as to why the stepped porting plays such a huge role in the quietness?

I can't find them on my favorites on my phone. It was up on the nation not too long ago; I remember playdoh showing me it.
