After using this Tippmann for a year and probably playing with it at least every 3 weeks I have to say I can give a pretty biased review.
"Tippmann" that is a word in the world of paintball that often accompanies reliable.
Unfortunately the X7 doesn't deserve that title. The 98 does, you can throw it in mud or neglect it for a year and will still function the way it was when you first played with it. The X7 on the other hand isn't of the same caliber. The cyclone feed system is too powerful or something because the PLASTIC pieces have stripped out on themselves on me and have caused it too jam. if any dirt gets into the internals the X7 won't cock correctly and you'll have too do it again manually. And too keep it in good working order i have to take it home at the end of the day and strip it down and clean it every time I play with it.
I don't know what Tippmann was thinking putting so much plastic in this gun, maybe it was special ops paintball getting into their heads. But heck if you want a gun that simulates weapon malfunctions the X7 is the marker for you.
The marker is cool looking and is accurate but that is probably all I can say for this marker.
All in all the gun is looks but no heart, and in my opinion needs a re-evaluation by Tippmann.
You obviously rely too much on the mechanics of a 98 custom. The only issue with the X7 can also be the issue of the A5, which is the cyclone feed system. For any Hopper/Loader.. if you get mudd or dirt inside, it won't function as well as it should. Its common sense. The X7, A5 and 98 all share the same internals/mechanics from each other so i doubt the credibility of this asinine review.
