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.

I do have, what I think is, a Colt semi carrier with no bottom. "half circle".?? But am unsure as to maker and didn't weight it.

Mine has a "C" stamped on the left side, if that helps you authenticate it. ??
