I have a upper from Precision with kreger barrel it's stupid accurate it's a one hole gun at 100yds
That's what I would expect from a Krieger barrel, or a Lilja, or Bartlein, or LW, and some other top barrels. I can easily shoot 1/2 inch groups at 100 yards with a variety of my sporter hunting rifles. One in fact I just got is a TC Compass in 308 and it's a very light weight barrel and even lighter weight polymer stock. Surprised how well that rig shoots.
