Some of the smaller MCH arms look like Handguns in my tiny lalafellin hands. Honestly, it's not a huge problem.
The Gauss Barrel/Toilet Doily floats in space, but it already doesn't make sense so that doesn't bother me much.

I think a set that had a different/got rid of the Hip-kit thing that all guns had would be cooler.
