This is a great gun. Performance wise it shoots pretty hard. Mine came out of the box shooting 371fps. It also has great accuracy, So far i've only shot it at about fifty feet but it hits right where you aim. In general it's very solidly built: full metal with a nice weight. The description says only the rear sight is dotted but mine came with the front one dotted as well so thats a plus. It's worth the price.
I only have two problems with this otherwise perfect gun.
First, I absolutely hate the look of the conical barrel. I actually meant to buy the Mk. 2 because of that, but I ordered this one by accident.
Second, The magazine releases sometimes hits the side of my OE tech fast-draw holster and releases the magazine. It's not KWAs fault but it still sucks. I need to either fix something with the holster or the magazine release or risk losing $30 magazines...
-Shoots about 370fps
-enlarged magazine port for easier reloading
-ugly conical barrel
-magazine release problem
