Faxon fluted barrel - Faxon Firearms 5.56 NATO Rifle Barrels, Heavy Fluted

I bought this barrel for an HBAR style upper build planning for "middle" price point total cost. I purchased the Faxon based on recommendations of a friend and "professional" reviews and various blogs. I have not used the barrel yet but have used the go and no-go gauges with the bolt I will be using and headspace is appropriate. The barrel finish is clean with no machining marks. I am reluctant to give it a final star rating until the barrel has been used. Will update review regarding accuracy as the barrel is in service
