Faxon Duty Series 16" Pencil, 5.56 NATO, Mid-Length, 4150 QPQ Nitride AR-15 Barrel

I bought this barrel for a lightweight/home defense build (~6.5 lbs fully decked out). The fit and finish was great. The only think I wish is that there was an option to have the barrel dimpled for the gas block I also bought from Faxon, Please do this!!! Or if you'd sell a gas block jig so I can sweat a little less when I have to dimple the barrel myself. The end product I built is a great shooter and pretty accurate for what it is. No problems with any of the ammunition that I've used with it thus far. Definitely love this barrel and I'm looking forward to using more of Faxon's barrels in the future.

I recently got a system from Faxon. It’s an AR15 which consisted of a 16” pencil barrel, their new flash hider/ compensator, the Holding Upper and lower, a Faxon bolt carrier assy and a Hyperfire trigger. I took it to the range today and shot 5 rounds through it to get it close, I was using a Nikon 3-12x42 power scope shooting at 100yards. I put up a target and took my first shot. Made a quick windage and elevation adjustment then fired 4 consecutive rounds. I had 2 bullseyes and 2 just off dead center. The grouping was 0.950”, the ammo was cheap 30 cent a round Winchester 5.556/.223 ammo in the white box from Field and Stream. I was just laying the gun on my range bag Imagine what a good shooter, using match ammo and on sand bags could do. I bet you would hold 1/2MOA Thanks Faxon!

Barrel head spacing was correct. Barrel length was correct. Muzzle threads were correct and crisp. Barrel extension was correct. Gas port was properly sized for mid-length gas system and located correctly. Finish was complete and nice. Notes: All in all this is a great barrel, super light, correct to specifications. The value of this barrel is also another great point. I have used more expensive barrels that have the same attention to detail and workmanship as this one. The barrel is surprisingly accurate for its weight and the reduced rigidity found in pencil barrels. would recommend for use.

This barrel is everything I expected, finish is flawless, markings are sharp and clear, and the inside of the barrel was beautiful upon arrival. I just finished my first range day with this barrel and I couldn't be happier, it groups tighter than me when I shoot offhand, it does heat up quick but it is so skinny it is to be expected. I doubt I will ever look anywhere else to buy a barrel for myself in the future. Wonderful product

Wanted to do a lightweight build, heard about Faxon Firearms pencil barrel and talked to friends who use them. I was not disappointed, used with BCM Kmr 15" forearm it turned out fabulous. My wife shot it after I sighted in irons and red dot. "Thanks for my new ar honey, it's so much lighter than mine"! Yes dear your welcome.

I'm building a light weight rifle and the pencil barrel was what I needed. Faxon has the lightest pencil barrel at a great price. I'm very happy with my purchase.

So far I am impressed with this barrel. It is nice and light, exactly what I was looking for. Everything is a perfect fit when paired with the Faxon low profile gas block and gas tube. As far as accuracy: when in my untrained, hobbyist hands, I put 30 rounds of American Eagle 5.56 55gr FMJ all center mass at 100 yards with iron sights, good enough for me. I definitely recommend this product and will return to Faxon on future builds.

I purchase this for a light weight AR-15 Rifle build, and this barrel is the lightest I've seen so far in the 16inch length with a mid-length gas system. The finish of the barrel is beautiful! it shoots nice and accurate as well. I will be creating a more detailed review for my youtube channel in the near future at youtube.com/BigGunner81 this barrel will also be featured in the his-n-her rifle build video series as well as the Washington State build of the 50 states of AR-15 project. Thank you again Faxon for making these awesome barrels!

We've been selling the Faxon barrels for just a short time but we've already re-ordered several times. Our customers frequently comment how great the accuracy can be with such a lightweight barrel. Keep up the great work! Brennan www.firearms4less.com
