I got the tactical kit- it is the same as the basic but it has a stock and m4 barrel shroud. I was very impressed with the barrel- it was the most accurate stock barrel I ever had. I upgraded the gun with a quickthread 98 custom, flatline barrel, but this really isn't necessary, unless you have 80 or so dollars lying around that you want to spend. The stock is very durable, not a flimsy 2 dollar piece of plastic. The mag-tool kit is very handy, and the curve in the mag well is great for a hand grip.
Aside from all of the great features, the one necessary upgrade is a cyclone feeder. I got one because of the e-trigger, but even a response trigger or a normal one should be accompanied by a cyclone feeder. The weaver mount installed on the carry handle easily.
Since I got the gun, I have had no problems with it. I have dropped it multiple times, smashed it against rocks and trees, and even gotten it wet. I would have to say this is the ultimate woodball gun. The weight (about 5 pounds) makes it an unwieldy speedball gun, but I'm not a big fan of speedball. This gun is cheap, but has the quality that easily equals or surpasses that of any other Tippmann gun. A perfect gun is rare, but I would have to say this is one.
