Tippmann X-7 Phenom, red dot sight, 12" JJ Ceramic barrel.
Tippmann A-5 with response trigger, other wise stock.
Very efficient - LP
electro and pneumatic modes
Easy to disassemble
Some ball breakage and minor leaks "out of the box"
I received my Phenom and shot a few hoppers of left over odd paint that was hanging around my garage. I had a few breaks which I attributed to the old paint. The marker felt great and all firing modes worked perfectly as I zeroed in the reddot. The next time I used it was at the huge West Point Combat Classic. Using fresh RPS Premium paint I was having terrible breakage. Tippmann had a tent at this event with techs doing on-site repairs. I took the Phenom in with paint dripping out of the barrel. The tech stripped it down and showed me the face of the bolt. A common production problem is some very sharp ragged edges on the 3 crescent shaped holes in the face of the bolt. He sanded these down and recommended that if this didn't work to be a bit more aggressive with a Dremel tool when I got home. He also noticed a very faint leak around the trigger pin plug. He tightened and greased everything up as he reassembled and the marker worked perfectly. I took his advice and Dremeled the holes after that event. Since then I have shot 10,000 rounds of different brands of paint without a single break. I have quit carrying a squeegee in the field!
Smoothing the bolt face and lubricating all of the small o-rings is essential pre-use maintenance.
The Phenom's low pressure operation makes it extremely efficient. I get about 1,500 shots on a 70/4500 tank. I always run out of paint before air. Just out of curiosity, I swapped to CO2 at the chrono station, and there was no change in the velocity from HPA. The built in regulator is amazingly consistant regardless of you gas source.
Operation of the Phenom is buttery smooth. To get to full auto you have to pull the trigger 3 times and hold that third pull. Some reviewers have found this annoying. It doesn't bother me.
Tippmann upgraded the cyclone feed from their previous models with new guts and softer paddles. There are no upgrades required and the cyclone will easily feed the markers 15 bps.
I mostly play woodsball and will tough it out in bad weather. For this reason, I historically stayed away from electros. The Phenom's 5 electronic firing modes work off a standard 9V battery. If you battery dies you can switch to strictly mechanical semi-auto mode and continue the fight. A great feature.
I love the Phenom.
Highly recommended for woodsball experts, milsim, and all recreational players. Fast enough, but too heavy for professional speedball.
