they can be related, light strikes can also be caused by by bounce (if bad enough) which a heavier buffer will reduce. >>63995554
I've see you mention JP captured springs for a while. If that works for that's cool but it's really not necessary unless there is some other deficiency in your build or you're chasing high ROF. I have a heavy barrel rifle length gas 16" build running perfectly in SS with normal milspec parts (apart from the SS itself).
