I couldn't say, I only shot Diblo Heat, (wich worked great).
Diferent bore sise options
Looks kinda like bamboo, (sweeet!).
Curves to the left (so little, I almost couldn't tell).
Loud, (to the shooter).
My bro' just got one of these, all I can say is WOW!! This thing was the flattest shooting barrel i've ever shot! We were just yesterday shooting things around the yard with it,. I called out like 10 targets at deferent distances and he hit all but one first shot! He handed it to me and then I shot them all too!! We decided to test the "Quiet downfield" property advertised by hammerhead, so I went and stood next to one of our tarets, (I had my mask on, of course!!) . He shot off a couple shots, all I could hear was a muffled "puh" and then the paintball whizzing by and smaking the target!! I wasn't quite ready to spend the $100, but now I'm convinced, this barrel is worth its wieght in paint!!
Verry good barrel, I would highly recomend it over all other barrels that I've used.
