I have tried PMing the member here on AO but it's been some time and still no response. I see a lot of varying results when it comes to pneumag pulls and their trigger pulls. Some seem pretty soft and easy to chuff and some seem like they can really rip. From what I've seen, the trigger results I'd like to get from a build if I decide to take that route would be like the one in the video below. Where it seems you can hardly tell it's mechanical at all.
