DPMS LR308 barrel suggestion for a build

[tp555]

Thats actually pretty good.Blanks in carbon from the major mfg's cost about $200.Add $60 for the barrel extension and $120 labor.That would go about $400 or so.Variations due to blank cost can be expected.Still most dpms barrels are over gassed.I sell a lot of gas blocks to those peeps.How they shoot? I don't know. I make ar10 barrels usually in special cals you can't buy ( 338 federal, 338 wssm.358 wssm, 308 also). Pricewise not bad.The rest I don't know.
