Hm. It has been awhile since I tinkered with the AR 15, but IIRC, the ejector is a button in the bolt face. When I used to shoot match rifle with mine, I trimmed 2 1/4 coils off of the ejector spring, and the brass used to land pretty much at my feet.
Based on this recollection, I am having difficulties conceptually figuring out how bolt speed would increase the ejection forces, as it is bolt speed one would be seeking to regulate with an adjustable gas block or maybe a faster powder, etc., and bolt speed would *seem* to be a variable independent of ejector spring forces?
