The Faxon Duty Series 4.5" Light Tapered 9mm AR-15 Barrel is a top-of-the-line upgrade for your AR-15. This barrel is specifically designed to provide reliable and accurate performance in a compact package.
The barrel is constructed from high-strength 4150 steel, which is known for its exceptional durability and resistance to wear and tear. The QPQ nitride finish adds an additional layer of protection against corrosion and other forms of damage, ensuring that this barrel will stand up to harsh environments and heavy use.
The light tapered design of this barrel ensures that it is lightweight and easy to handle, without sacrificing accuracy or reliability. This design allows for rapid target acquisition, fast follow-up shots, and reduced recoil, making it ideal for use in close-quarters situations.
The 9mm SAAMI chamber ensures that this barrel is compatible with a wide range of ammunition, while the lack of a gas port ensures that it is optimized for use with blowback systems. The no gas port design also eliminates the need for a gas block, making installation quick and easy.

Manufactured in-house, 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.

As usual Faxon has created a really great barrel. I built a small ar-9 PCC with it and so far I’ve put 200 rounds through it with 0 failures. I love their regular AR barrels and was curious to see if Faxon could pull off a PCC barrel. They definitely can. I will probably get a slightly longer one as well since I know it’s going to be a dependable piece of gear.
I spent quite a bit of time researching barrels before making my purchase. This is a lot of barrel for the money. I was very pleased with the quality and overall finish. I really liked the fact that the threads are 1/2x28 since I already have a suppressor mount in that size. The lightweight profile is a big plus also. While I haven't had a chance to shoot it a lot, I can say that function has been 100% and it has been plenty accurate for ringing steel plates with no trouble. I would highly recommend it for anyone building an AR based 9mm pistol or SBR.
