The receiver is very, very dark, the trades are ok; ICS branded.
As with most plastic receivers if you use and abuse, it will crack.
I have a crack on the pin hole for the trigger guard and a couple scratches, other than that; it's held up fine.
If you decide to tear it down often (might break a piston body or the bevel gear in the first week) the small hole in the receiver that holds the moulded slide catch; which holds the wires to the side of the receiver might start to wear out, just be careful when you take you the screw and it should be fine.
IMO itís a great moulded piece and well worth the buy... the internals are another story... but itís better to try it out for yourself, as the 2 Iíve dealt with were made on a Friday... lol
