 The Gunner profile is a blend of two of the best performing profiles of all time, Gov't and Pencil. Faxon's Gunner profile combines the durability of the Gov't profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter's body, limiting fatigue, and allowing for shooting, training, or hunting all day long.

Faxon Firearms barrels are the pinnacle of value. Manufactured in-house in Cincinnati, Ohio, Faxon 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 beginning of the manufacturing process.. 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 with precision PTG gauges.

    16" Gunner in 5.56 NATO

    Fast delivery. Impecable outside finish. First session at the range gave me 2" groupings at 100 yrds. using 62gr green tips. Super light and a better choice than the pencil profile.

    Outstanding quality!!! Even better price!

    Had not really heard of Faxon until recently and I should feel ashamed. I recently watched some Q&A vids with a favorite youtube channel InRange, they had a Faxon rep that blew my mind with info. I just had to try a barrel from Faxon and was surprised by all the other quality stuff they seemed to make. I cannot yet comment on the accuracy of my barrel but the machining and finish are top notch. The gunner is a gorgeous barrel to say the least, I cannot say enough that the machining is perfect. Even the laser engraved Faxon logo is very nice. The best part is they almost seem to hit the perfect price point for me. I didn't want a cheap barrel thats only accurate when it's ice cold but I can't justify spending 350-400 for a quality barrel. Faxon hit my heart and wallet just right. Needless to say, as funds become available I will be buying most parts for my upper from Faxon and will keep you all updated with the results!!! Love the barrel just buy it!

    Barrel looks great. Amazingly lightweight, almost scary after using heavy 18". Overall impressed with it.

    This Barrel is performed as good or better than I expected. I have quite a few barrels from Faxon firearms and I have come to trust in their accuracy, the craftsmanship, reliability, as well as their customer service. Feed ramps and extension are very clean and nicely done. Fit to my various upper receivers have been very consistent and borderline tight (this is a great thing). Great profile offers weight savings without jeopardizing function and longevity. With the right ammunition combination I am experiencing sub MOA groups. Highly recommend this barrel and many others offered by Faxon Firearms.

    16" Gunner Barrel is Perfect

    Posted by John in Tampa on Oct 17th 2016

    I have used the 16: Faxon Gunner barrel in a few applications and find superb accuracy, combined with great fit, finish, contour look and attractive over all weight package for the complete rifle. Great barrel and reasonably priced... I recommend this barrel for your next 16" AR platform build!
