Which gas block for suppressor

[PNWTargets]

The dwell time is when the bullet passes the gas port charging the system until the bullet exit the barrel..Using a suppressor increases dwell time.. The buffer or spring weight has nothing to do with holding gas pressure..

BCG dwell is when the BCG moves from static (back/forward). Spring pressure does affect this dynamic movement. When the BCG is still static as gas flows to it, that has to do with holding gas pressure. Possibly I am not explaining what I mean clearly.
