Pirahna STS with: Armson 16in, 9 volt hopper, and sight
kick'n (don't ever use big ball)
this barrel is wicked amsome, it is very accurate (goods for picking of guys that have small body parts hanging out, and shoots longer then anything i have seen, less than a boomstick
picky with paint, , hard to clean except if you get a straight shot then cleaning is a breeze. besides that nothing that makes it not worth the money. it is definetily worth it to get one i think it is the best barrel out there
better then boomstick for the money and accuracy and range,and everything, so if you have the money and are looking for a good aftermarket barrel go out nad get one.
