I have a model 98 with a 12'' dye ultralite barrel, ACI sub-zero 6 chamber expansion chamber, double trigger, phyco ballistics drop forward.
EXTREMELY ACCURATE! I shot a 2000 case last time i played, didn't break one ball! It's fairly quiet, and hence the name its ultralite. You can also lay balls on top of each other at far distances. It's good for speedball or woodsball your choice.
The only bad thing was the week of anticipation after I oredered it. Some think the price is a little steep but it's absolutely worth it.
If you have a tippmann 98 stock barrel this is a must!This barrel is amazing!
