Manufactured in-house, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy. 

Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

    Always Buy Faxon First

    Posted by Owen McDonald on Oct 11th 2018

    i Bought two barrels before this one from another manufacturer that guaranteed 1 MOA at 100 yards and get either of them to go under two MOA at 100 yards so i finally got fed up enough and came back to what i knew would be a solid barrel here at Faxon and i couldn't be happier it shot well under 1 MOA at 100 yards on a day with rather trying conditions i should have stuck with Faxon in the first place and saved myself the headache my customer is more than ecstatic with this build and its Faxon that brought it all together

    Quality

    In all fairness I have not assembled my AR using my Faxon barrel yet, so I cannot attest for accuracy or anything like that YET!!!! But what I can attest to is the overall quality of the barrel and the level of commitment from their customer service. I was really wanting one of their 18" 4150 rifle length in 5.56 socom barrels but they sell out so fast that I can never get one, so I purchased the 20" instead. The nitride finish is flawless inside and out, m4 feed ramps nicley cut and polished. The general fit when inserting the barrel into the upper is good very little wiggle...admittedly the wiggle is not a barrel issue but more of a reciever issue, it needs to be lapped to the barrel. If I had any complaints it would be that the barrel does not come pre dimpled so I wouldnt have to ruin the nitride finish...but again in all fairness I think they dont do that becuase different gas blocks have different dimpling points...maybe I dont know.
