Picked this up when I made my Tower Hobbies order for my B4.2RS and it seems that it is a reasonably quality piece as it is machined accurately and fits well . I do wish the anodizing was a bit thicker or more durable as I have already scratched it in a few places and eventually it will be more silver than gray but since I bought this for its improved strength vs the stock piece and its low cost I suppose I shouldn't complain too much.
