Its quieter than my spyders stock barrel, and a lot more accurate, very sexy barrel.
not as quiet as i hoped, probably because my spyder always sounded like a cannon.
This is a great barrel for my spyder, its performance is slighty better than the night stick, and the performance is very similar to the teardrop, both which are about the same price. The barrel you pick is a very important choice, and for around $40 dollars now a days, this barrel is a very good price. If you want to quiet your gun down some, and want the added accuracy, this is the economical choice for a beginer to intermediate paintballer.
I would definantly buy this barrel again, its really quiet compared to other barrels ive tried.
