Not sure where you're getting your size refernces... here is the SoB with bolters, about the same scale as mine..
And here is a shot of the scale of the hand flamer...
These where built for a Sister of Battle suit. They are not ment to be life size Space Marine scale, who would stand some 8 foot tall in their armor...
