Size Chart

Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, 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.

    Barrel is great quality, I've not installed it yet I'm waiting on a matched set of Upper and Lower to become available on your website to put it on. I also bought the SA adjustable gas block, quality is good again pending install on my new Houlding lower/upper.

    I would be pleased if you could give me an ETA on the lower and upper availability...

    My company just started making parts for Faxon, we are excited about growing the relationship.... great products from what I've seen.... Brent Kirkham 260-229-0717

  • Top shelf quality!

    Purchased this barrel because it ticked all the boxes I needed for this latest build. I've used barrels from other manufacturers in the past similar to this but I'd have to say this is definitely my barrel of choice here on out because of its quality and finish! Can't find a single thing I could comment on in any negative manner. All cuts, threads, ramps, lugs & gas port are spot on and super clean. Finish is perfect! H-BAR barrel cut with flutes makes the weight very manageable up front while still benefiting from the heavy barrel design accuracy.
    Thanks Faxon for a true winner!

  • Perfect fit and finish

    The Faxon 5.56 heavy fluted barrel fit my Seekins Precision SP223 upper perfectly. It also looks great installed on the upper. I haven't shot it yet, but I have no doubt that Faxon will live up to its name in quality. Highly recommend for your build!

    I recently bought a barrel from faxon firearms it was the 16" heavy fulted 556 I want to first start off with their customer service it was excellent and a pleasure to order from them I had a couple questions about my order and they return my call that same business day and then shiped my barrel immediately it came in a really Secure barrel tube so it would be protected from being damage from shipping when I receive the package it was three days later from when I ordered it and the barrel was flawless definitely Worth every penny you could almost say it's under price for what you get with the product and the customer service when I installed the barrel it had a very good tight fit to my Upper but not too tight where you have to beat it in and risk Messing up threads the barrel it had little to no break in time It need to go throw it shot like a dream right out of the box And when it was all done the headspace was perfect straight from the install but I would still recommend highly to still check your headspace on all new builds or barrel replacements always better to be safe than sorry On the first day I sent around 500 rounds through the barrel and I Had no problem cleaning the barrel the barrel I highly recommend their barrels and their company as a whole I will look forward to doing more business with them in the future
