Best lightweight 20-22" barrel for accuracy and lifespan (durability) ?

[PredatorDown]

I would absolutely recommend the JP barrel. I run their 22" heavy profile and couldn't be happier with it. Currently has over 3500 rounds through it, and will still consistently hold right around MOA out to 1000 under decent conditions. The hardest part of load development for me was deciding on which 1/2"-3/4" group to pick, since almost everything shot in that range.

I haven't personally owned or shot a barrel from PF, but from everything I've read here and elsewhere I wouldn't hesitate on picking one up. I just don't have any firsthand experience with one
