Its quiet! Major improvement in accuracy if you match the paint right!
One thing I had to do was add an o-ring at the end of the barrel so it wouldnt come un-loosend.
This is a great barrel. It is quiet, accurate, and it looks great. When I say quiet, I mean quiet. I noticed major improvements in accuracy over the stock barrel. The green end of the barrel goes well with the gun. I have also noticed that if you dont match it with a paintball that is the same bore as the barrel, you will break a lot of balls. Mine is standard bore, and I have found that RP Sherer works great with it. If you have the right paintballs, this is a great barrel for anyone who wants major improvements in accuracy, and noise.
