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.

  • Lightweight Awesomeness

    Posted by Jon on Jul 3rd 2018

    I’ve bought several of these and I couldn’t be happier. Accurate without the extra weight, these make an excellent all around carbine. The mid length gas system is perfect. Honestly, it’s unlikely I’ll ever build another AR without buying a Faxon barrel. I’m that in love with it.

  • 14.5 pencil barrel

    All around great barrel. 1 issue though. The feed ramps are rough, alot of tooling marks. In my opinion the ramps are unacceptable. I can polish them out but I will be removing the finish to do so. Not happy about that.

    Faxon Staff Note - We're sorry to hear that and ALWAYS happy to ensure your satisfaction. Contact our customer service so we can get you an RMA label!

  • Why spend more for a less quality barrel?????

    Posted by Jeffrey Mitchell / SRTLLC on Feb 28th 2017

    I've built multiple rifles for clients using the Faxon products, specifically the barrels. Having nearly 35 years experience as a gunsmith and high end custom weapons building, it's a real pleasure to use such high quality products, that are very reasonably priced! I believe in the Faxon products, enough to use them for military, law enforcement, and more recently my wife and daughter's custom rifles!

  • The best barrels currently out

    Posted by Matthew on Feb 20th 2017

    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.

  • Quality barrel

    Posted by Joe on Feb 14th 2017

    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.

  • Best Barrels in the Business!

    Posted by WA on Dec 28th 2016

    These barrels are the best of both worlds: light and extremely accurate!

  • lightweight Build

    Excellent quality at an affordable price!

  • Amazingly Light

    Posted by Unknown on Jul 22nd 2016

    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.

  • Excellent barrel

    Posted by Howard Wilson on Jul 20th 2016

    A very well done barrel. Exactly as described, and really light weight.
