Looking at the sprue shots, there looks like some inconsistencies in molding. Sprues 1 (small parts), and 4 (shield and other parts), in addition of large sprue gates even on small parts, require some clean up - not much fun, especially on all those small parts. Sprue 2 (wheels and trail legs) appear sharp and well defined. Sprue 3 (barrel, recuperator, etc.) are soft-looking.
I must be getting spoiled by companies like Flyhawk and T-Models!
