There exists so many variables when talking about barrels that its all in the experience of each individual. Gun build,components used,ammo used,and most important,quality of shooter. I have used pretty much everything thats available and had great success with a few a terrible results in comparison from quite a few. I had an Adams&Bennett SS fluted barrel that was insanely accurate.Sold that gun to a friend and hes won medals on numerous occassions with this gun. Turns out, they were sold in Walmarts in the US for about $120. I have and have owned Dlask barrels that shoot exceptionally well. As far as Kid Barrels go, I have had nothing but the best experiences with them as well as their awesome triggers. Volquartsen barrels are great quality but real pricey in comparison too most. The two i had shot really good but not equal to the Kidds. These are just my experience but Ive heard lots of great things about IBI and Canadian is just a big bonus. Next build Ill give them a Whirl,
