Heck, I lost my mind and ordered the Slam Piece earlier today. So I have the black clone coming, and the authentic brass coming.
Now that I've had the clone for a few days here are my thoughts.
For what it costs it's a great mod but not without flaws.
It hits like a freight train, feels good in the hand, and it looks awesome.
Issues: (minor to me for the cost)
When I first got it I hated the firing switch, it was extremely hard to press.
Now that I've had it and used it a quite a bit it's much easier.
The fact that it's easier to press the firing button enhanced another issue though. The locking mechanism is a good idea but the firing switch is actually party of the tube itself. It gets easier to push because it eventually gets pushed in slightly (bent), this creates an issue with the lock mechanism. The lock mechanism is a delrin tube with two notches in it. When either notch is lined up with the switch it will fire, when the delrin is in front of the switch it won't fire.
When the firing bar gets bent in slightly it catches on the edge of the delrin when trying to lock it. That and unless you loosen the bottom cap it is really hard to turn because the battery is tightened down on it.
Those are minor issues to me because the way it is designed it would be really hard to accidentally fire it in your pocket or anywhere else for that matter.
I'm not unhappy that I bought it (I even ordered another in silver) but I would really like to hear how much better the authentic is.
