  • Product Description

    Our pencil barrels are the lightest in the industry. Don't take just our word for it, major companies like Robar, 2A Armament, and others choose Faxon pencils for their ideal balance of weight and performance. 

    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. 

    Faxon manufactures all our barrels in Cincinnati, Ohio under our ISO:9001 and AS:9100  quality certifications.

    1. The best barrels currently out

      Loved the barrel so much I bought another within 1 week. Barrels are very light and take weight of the far end of the rifle which helps to better balance the rifle making it feel even lighter then it is. Accuracy is right up there with my $450 stainless 416r poly rifling barrels. I have the barrel paired with a lightweight bcg and SLR sentry 6 adjustable gas block and will be running this setup with ALL future rifle builds. on 20th Feb 2017

    2. Quality barrel

      I am a full time LE firearms instructor with a State police academy, and have one of these barrels installed on my primary training rifle. It is the lightest quality barrel I have been able to find, period! I have this rifle slung hours on end, and appreciate the reduced weight. With that said, there is no sacrifice of accuracy for the weight savings. These barrels are very accurate as well. I have purchased 3 of these barrels and all of them have performed flawlessly. The fit, finish, and quality are unequaled. I couldn't be happier with the customer service that I have received from Faxon! They are a great people, making quality components. on 14th Feb 2017

    3. Best Barrels in the Business!

      These barrels are the best of both worlds: light and extremely accurate! on 28th Dec 2016

    4. lightweight Build

      Excellent quality at an affordable price! on 13th Oct 2016

    5. Amazingly Light

      Barrel went through a tough journey getting to me (showed up in a roughed up tube after being lost in the mail), but was well enough packed to not take any damage.
      Threw it on a light weight build with a pinned/welded muzzle device, and managed to hit the paper at 1.5 moa at 100 yards even though I'm a (really) bad shot.
      I would recommend these barrels to anyone and more than likely will be buying more in the future.
