purchased this barrel for my first ar15 build and so far im very pleased with the product. barrel arrived a little dirty but cleaned up with no problem, installed and as of now have about 100rds through it. ive shot PMC .223 bronze,lake city 5.56, and tula .223, all fmj. barrel does not like the steel cased tula ammo at all constant FTE but no problems with other rounds which are brass. as far as accuracy goes i havnt done any group tests or anything, i did zero in my iron sights and i could pretty much hit anything i could see when shooting around 40-50yds. only thing i can complain about is i think the parkerizing could be better, seems like it scratches to easily although this being my first ar15 barrel i dont really have anything to compare to. I will update my review soon when i get some more rounds through my ar and ill test its accuracy alot more to see just what the barrel can do.
