It is a large bore barrel and the paint sold at my field is mediun/small bore, so it doesn't work as well as it could, but it does shoot the larger cheaper paints decently.
The chrome finish comes off very easily
Long range accuracy is downright sad
It is loud.
Don't waste your money on one of these. A good CP barrel is quieter, cheaper, more accurate and gives you a choice of legnths and bore sizes. I would not reccomend this barrel to anybody.
