My only understanding of the buffer / buffer spring assembly is how it impacts the bolt locking back during end of cycle, controlability, and a smoothing influence on the overall operation of the weapon. And perhaps smaller things such as direction and distance of ejected brass, etc.
My question is, if a carbine buffer, H through H3 buffers all lock the bolt back upon last round fired, which buffer would I want to go with and why? Does one "beat up" parts than another? That's about all I can think of but I have no idea. Though I don't know, I don't see where one size over the other would play a major role in the bolt slamming forward unless there was a major difference in springs..
