Stag Arms .308 AR barrels...how's the quality?

[Tengoo]

I'm looking at building a second upper for my LR-308. A Stag Arms 18" barrel is available at a decent price...but how good is it? I'm looking for better accuracy than the stock 16" DPMS barrel...

Any knowledgeable commenters out there? Will the Stag Arms barrel have better than average quality? Any experiences?

Thanks in advance...
