F4 illustrator 4-stage x-chamber nothing fancy but good gun
anything really this barrel has such a huge bore on it(.692) i believe. Big paint is better such as nelson, but shoots zap, proball, crap paint you name it just no diablo hellfire or really small stuff.
This barrel is pretty quiet
not a horrible price
Ball breaks cause ufo's(what doesnt?)
Big ass bore makes squeeging hard(need a swab to effectivitly clean)
This barrel is pretty kickass! I bought an All american and didnt notice a bit in accuracy or quietness from one barrel to another. I like being able to shoot cheaper paint and the big bore doesnt cause accuracy problems. Good barrel for the money i would recommend it highly
