blue vsc phantom, T-Stock, clear parts, 8 inch Fr-antom barrel, SS Freak inserts, 7.5 JJ Ceramic barrel.
No upgrades are required for Phantoms. The stock barrel is very high quality and will shoot just as good as any aftermarket barrel if you have a good paint to barrel match. Some people will invest more money into their phantoms to have it be their own; aftermarket barrel kits, undercocking kits, custom made grips, different stock feeds, regulators or stabilizers etc.
Overall Phantoms are incredible markers.
Some screws can loosen up during game play.
Phantoms are a great gun for someone on a limited budget or are looking to improve their game. They force you to concentrate more on how you play than how fast you can shoot. In my opinion every player can benifit a great deal from playing with a pump marker instead of a gun with an electric trigger.
For the price Phantoms are top of the line. I have owned and used quite a few different pump markers. Though some of the higher end will always be considered better, it always comes down to the player and what they are more comfortable with. I owned a 775 dollar Buzzard, but in the end I sold it off because i was just more comfortable with my phantom.
The only thing I can think of to be improved is that some of the screws do not stay in place. The screws for the T-stock can become loose during game play and fall out (easy fix, less than a quarter at your local hardware store for new screws). the screw that keeps the safety tight also loosens up and can occasionally get in your way during a game. Those are the only things that I can think of that could be improved on this marker (can easily be improved on your own with a little bit of teflon tape or blue lock tite), but for the quality of the marker you are getting I would say that it is worth every penny you spend.
