Ballistic Advantage makes very good barrels that are in fact concentric to the bore. Any quality manufacturer will likely have a properly aligned barrel. If you really doubt it then send it in to ADCO and they can check it out for you.
IMO people put way too much emphasis on this, just like headspacing. It's really a non-issue and is nothing to worry about unless you're buying garbage $60 barrels from a no-name somwhere deep in the internet. |

Thanks for the info. I agree with you. In the end I am really just looking for the least POI shift for my money.
GreenM4Guy posted this in a thread a while ago "Most production barrels, are anywhere between .001 - .010 off. The best barrels ive seen are noveske, BCM is usually pretty darn good. Bushy not so hot, CMMG not so hot, DD pretty darn good. Colt is ok. When we thread a barrel we indicate off the bore to with in 0.001 everytime. but we're also not making barrels by the hundreds. We can afford to take longer and make sure its as close to perfect as it can be. Just my opinion, take it for what its worth. " |

Thread concentricity wouldn't effect POI shift- it would cause possibly a baffle strike on the endcap of your suppressor.

I got a PSA 10.5" premium FN barrel upper with bcg for that price range a few months back. It is a great upper.

My PSA 10.5" with my 762-SD works great, no accuracy issues what so ever or baffle strikes.

I'd highly recommend it. |

I have the 10.5 inch version of this barrel in .223 wylde. Shoots straight, groups nicely, and I have an AAC 51t on it, and zero baffle strikes to date. |

My strategy is to buy a longer-than-required barrel, and a have competent 'smith cut and re-thread it. My suppressors are just too valuable to me to trust most AR barrel manufacturers.

You can have the barrel checked for coincentrocity.. Any decent machinist can tell you whether you are good to go or not. When it comes to this issue and accuracy .01 makes a big difference.. |

They can add threads without losing length.
