I’m working on a 27” barrel for a ar in 17 Remington. It’s taking a lot longer than it should but I don’t have all the nice fancy tools either. Anyways I started thinking and comparing different lengths of barrel vs gas system and came to the conclusion that a standard rifle length gas system might be way to short for a 27 barrel. I want this to be smooth and not beat itself to death. Has anyone experimented with this? I was thinking of getting all super scientific and stretch it out to 20 then start lightening bcg, buffer, springs till I got it to function (if it wasn’t already) have anyone blazed this trail for me? Can anyone claim it won’t work and give a decent argument why?
