Sig does it again with an amazingly realistic MCX Canebrake. It weighs and looks the part, signifying a quality build. I put countless shots through it at the range expending one entire 88 gram CO2 bottle, and it fed and worked flawlessly. The pellet belt mechanism is easy to load and install. I had been doing some research into getting and using a 12gram CO2 adapter, but generally the "internet" said that the Umarex adapter would not work in this gun without modifying the receiver. This is NOT true. It fits and works, which will save some money. You won't have to worry about leaving unused 88gram CO2 cans in the rifle as you will either a) expend the two 12grams more quickly, or b) even if you want to pull them to preserve your seals - it's only a couple of dollars instead of $15.00 tossed out. Great addition to my collection.
