ok i finally got everything figured out (a few hours ago) but i must say, this guide is very vague for people who have absolutely zero experience with mags... you might want to fix that
i got it to the stop leaking part but i ran out of air so it still isnt tuned

but something kinda weird happened, it stopped leaking at the 2.5 carrier but still wouldnt shoot, so i put in the 3.0 carrier and it started leaking again and still wouldnt shoot, so i went back to the 2.5 and now its leaking

. but then i put in a different bolt spring and it stopped. someone explain please...
oh yeah and my bolt springs are nothing like the ones you are talking about, theres a green one, a neutral kinda brown/grey one (not bronze) that is shiny, and a dusted silver one, but i dont have red, and green wasnt in this manual, so...
