I am usin a Tippmann 98C with a 14" DYE xcel /16" Freak JR. barrel, Dye Sticky grips, a 3 stage GTA Expansion chamber, 12v Revy, Tasco Red Dot Sight, a Shocktech drop foward chrome, and a double trigger.
i recommend Marblelizer, Midnights, PMI Super swirls, and point blanks dont work too bad.
This barrel is amazing. Very customizable, it has amazing accuracy, for example while i was playing at a field i nailed 3 guys from about 100 feet and i didnt even have to tilt the gun back and my FPS was at 250. its very consistent when it comes to accuracy even when ur nitro/CO2 is low. its rather quiet, and the barrel is very light..
nothing other than too some people it might be a little pricey, but i thought it was worth every dollar.
Its an amazing product, very customizable and it looks great too!
