A 9mm AR pistol might be the most fun of all the ways to shoot one of the most popular calibers. In an AR platform that is more compact and mobile than a full rifle builds, you have the same low recoil versatility that 9mm offers. With our 9mm Pistol Upper Build Kit you can build your pistol with little hassle, and low cost, and have it set up just the way you want it with all of the options that we keep available for you.
This barrel is 4.5-inches long and chambered in 9mm. It features a medium profile and has a 1:10 twist rate. It is crafted from 4150 CMV with a nitride finish that keeps it strong, durable, and corrosion-resistant.
