I've been using this barrel for about six months now and I have never had a problem with it. It's very accurate and a great for the price it is. My suggestion is to tighten the connection between the barrel and insert as tightly as possible, so if you do happen to chop a ball the entire barrel will come lose more easy and clean it easily.
Conclusion:
I would recommend this barrel to anyone. You get your money's worth out of this and you will never need another barrel.
