Other pieces included

Gun Shield, narrow Rotor Shields with and without “ears”, co-ax MG Shield, co-ax cal. .30 MG including breech in resin.  All parts are cleanly molded except for the co-ax MG Shield which has an air bubble.  The Gun Shield fits the Tamiya M4 and DML M4A4 turret openings.  The mounting fasteners on the Gun Shield are shown proud when they should be countersunk flathead screws.

The red outline is the correct contour, the black is what comes in the kit.  See my article for a further explanation.
