Its is a very quiet and accurate barrel. The opposing team doesn't know what hit them. Ball breakage isn't a problem in this barrel. It adds atleast 25 ft. to my shot. You can't go wrong with a rifled bore.
In the time i have had this barrel it has been problem free.
I use a tippman pro/carbine gun with the armson stealth barrel. I use pro-ball paint. Works great. Overall these are a great combination for me so far.
