But, I don't see the need for heavy H3 - H4, or heavier unless your over gassed because of gas port size. You make a great point on ejector springs, there often over looked. I check my ejector spring tension by slowly manually ejecting a live round & watching for the rotation of the ejected live round. It should have good horizontal rotation, if rotation is only a turn or 3 it's getting weak. Should rotate multiple times when ejected slowly if ejector spring is good. As to buffer springs, I do run chrome silicone buffer springs even in my rifle length systems. Thanks for you information, and exchange of thoughts.
