Got this off Ebay for £8, unsure yet if it's going to build up well, I suspect it will, as most of it is PE, and small PE parts at that.
the plastic parts look like something out of a Cornflake box on first glance, but the moulding of the guns is fine and scale. This is one of two of the same frame.
here's one of the twin guns in close up.

some detail from the instruction sheet, this is just part 6
hopefully, when I get around to building the second of my MTB pair, this sub kit will add an extra dimension of detail to the forward guns
