I've now made a start on the rear end of the model and have detailed the exhaust assembly with some etch, cast off resin and some scratch. The pipes although not the best are an improvement over the kit items. A smear of mr surfacer later will sort them out nicely. The gun lock was very poor in fact it broke up whilst trying to clean it up! I managed to salvage the central portion so scratched the rest. I'm not impressed with the cast off stuff to be honest. Far too much clean up of very poorly cast parts.
