Just got my new Bushmaster/Blackwater Lower reciever, had to do a bit of modifiying the holes where the body pins go into did'nt match up perfectly and it seems like the Blackwater logo is a bit smaller too. I'm impressed by the detail of the Busmaster Logo though pretty accurate except for the missing armalite. The balck water logo does'nt look as crisp in the photo (probaly cuz i have a cheap camera) as the actual thing.
Here are some close up photos of the trades.
