The CCI phantom has many good points. It is, in my opinion, the best pump marker, for the price. Ok, on to the good points...
First, it is very small and lightweight. I had a VSC phantom with adjustable t-stock, .45 frame and green acid wash anno. I played MSC (modified stock class- with a tank on the VA) and a 16 oz tank on the vert adaptor added alot of weight. I would suggest a 3.5 or 4 oz tank for the gun.
Accuracy was excellent. Off straight C02 I was getting +-7 fps, which is pretty amazing without a reg of any kind even when running verticle bottle. Nitro actually did very little when I tried a crossfire 88/3k tank on it. With a good paint match (the stock barrel is just a bit smaller in bore than a .689 lapco or a stock imp barrel) my grouping from about 120 ft was 10 inches or so (estimated). If you want to further improve accuracy, look into either running a palmers stabilizer on the verticle adaptor and running bottomline, OR you can look into a sideline stab (recommended).
The stock barrel is very accurate, you don't need to replace it unless you shoot a small or large bore paint.
The verticle adaptor can hold large tanks with no problems, it is not flimsy, do not worry.
The gun is very easy to field strip with no tools, just unscrew 2 thumb screws and slide the hammer assembly out. You can replace the springs easily for major velocity adjustments.
Very good price for what you get!
The nylon set screw can come loose easily and affect consistency. I kind of, kind of don't like the bolt design. The TPC allows you to adjust velocity with a flathead screwdriver in small increments, and it quiets the gun a bit. But as stated before, it can come loose and change your velocity.
I broke in the gun; by that I mean I used it for a couple months. The pump action became considerably smoother than when I got it, but not as smooth as a higher end pump, EG carter or sniper. Not a major complaint :)
There aren't very many upgrades, so if you like to tinker (like me) then you will get bored with this gun.
That is pretty much it! Nothing major in the bad section, I could not find real fault with it.
I was happy to have owned the phantom for a number of months, but sadly I sold it to pay for tournament fees this summer. Oh well, I will probably buy another pump somewhere down the road- but it will probably be a sniper II. My reasons for this are: will take cocker barrels, so I can put a freak or other barrel system on it to fit the paint, it can be switched over to semi as a backup, and it can be upgraded to no end :D
I would suggest this marker to anyone who wants to play just pump for awhile, while not wanting to spend over $300. If you have more than $300 you could grab a sniper II and an upgrade or two (barrel, grip frame, reg etc.). All in all, I was very impressed with this marker, and I am glad I bought it (which is not what I can say for many of the other markers I have owned in the past).
Actually they are making freaks now for phantoms, and also, a sniper 2 or a ccm s5 would be a lot less balanced and alot bigger than the phantom. So the pump stroke advantage is at the cost of profile and weight,
