This comment had me curious about back pressure , so I just slapped the zero G on my 12.5” 6.5 Grendel to test vs my Hyperion K and harvester evo .My primary hesitation with the airlocks has been that I assume they must be pretty high back pressure to achieve such good suppression in the small packages. The primary downside I’ve experienced with cans is seeing premature pressure signs and sticky bolt lift from what seems like back pressure fouling or contributing to condensation in chambers. Maybe that isn’t the case but I’d trade some suppression, size, and weight if necessary to deal with that shit less.
For what it’s worth the evo and zero G had nearly identical ejection patterns and similar gas from the ejection port . The Hyperion k had less gas but was louder and sparked more .
