I've got a Tactical solutions aluminum barrel mounted in a Dlask receiver, Dlask innerds and a Kidd single stage trigger. Was getting 1/2 inch groups at 40 yards running federal automatch prone from a bi pod. I've had zero issues so far in about 3000 rounds. The only thing with this barrel I see is where the bolt touches it, it seems to mark it up a little more than a steel barrel. I have heard they can mushroom in this area, but I'm not concerned. I've had zero fouling problems unlike one of my tighter chambered guns. I haven't tried a Kidd one yet but here great things about them as well.
