I've got a 10/22 with 12.5in Dlask Barrel. Good accuracy for me, 1/2" groups at 50 meters.
From my understanding, Dlask barrels are re branded Green Mountain Barrels? I think Green Mountain supplies Dlask with barrel blanks for machining...or something like that.
ive got a couple Dlask barrels and i love them but ill be honest, i believe that Kidd barrels are gonna be your Tier 1 barrel and the Dlask would be just a little step down from there.
