Cool. Thanks Dano. Was pondering this the other day for some reason wondering if the E-carrier would be slightly lighter b/c of the segmented rail that interfaces with the upper and the longer cam pin tunnel. It is but not much.

Seems like running a Semi carrier give you a negligible weight difference. Less than 4% difference.
Cool thread, here are some of my contributions to add:

Just a general question about BCG's. I have seen some designated as M16 bolt. I am planning on building a mid length/16" barrel ar. Will a M4 bolt fit this or does it have to be M16? Thanks for any help.
