I sold mine, but experience was yes to accuracy but they are heavy! Mine shot a variety of Hornady factory ammo well. To include 120s, 140s and 147s. I settled on the 120s for my purposes.
i can't really comment on the price of the upper, and the rest of the parts but the barrels have a good track record on shooting well. Adj gas blocks are highly recommended along with HP bolts.
