Product Details
This is a solid barrel for anyone building or upgrading an AR9 pistol or short rifle. It's 5.5 inches long, threaded at the end so you can add a suppressor if you want, and the nitride finish means it'll handle regular use without much fussing. The 1-in-10 twist rate works great with standard 9MM ammunition, and it's made from quality 4150 steel that shoots straight and lasts.
