I had a Dlask 10/22 barrel, in a 12.5". It was just ok. Accuracy seemed acceptable for a sporter chamber, but it had bad vertical stringing no matter the ammo. I paid $210.
I switched to a 12" McGowen barrel and the accuracy is amazing and it's been flawless. The McGowen barrel did cost nearly twice as much though, and it's also a match grade barrel. Very nice quality on it, $380.
If I were to do it again, McGowen all the way.
Where did you get it?
