Nice but poor qc - ODIN Works Grendel/LBC Barrel, int gas placement, w/tunable GB, Stainless Steel

I waited almost 3 weeks to get this replacement barrel for my grendel build and was disappointed after scoping the barrel. There was some damage inside from drilling out the gas hole. It actually had a piece of jagged steel that bumped the borescope as it went through. I thought about somehow fixing it myself but for the cost I sent it back. I am not sure as to the effect of accuracy on the damaged rifling but sure the jagged metal would have damaged the round as it went through. I am now weary of some of these barrel manufacturers letting these leave the factory in this condition.
