The Davidson Defense AR-9 Mil-Spec Buffer Tube Kit is built for durability, performance, and smooth function in pistol-caliber builds. The buffer tube is precision-machined from 7075-T6 aluminum and finished with a black Type III hardcoat anodizing, along with a dry film coating to maximize wear resistance and internal lubrication. At the heart of the kit is a 5.5 oz carbine buffer, ideal for reliable cycling in AR-9 platforms.
The included flatwire recoil spring is crafted from heat-treated 17-4 PH stainless steel, offering consistent compression, long-term durability, and excellent corrosion resistance with its natural stainless finish. A phosphate-coated castle nut and end plate round out the assembly, ensuring rock-solid installation. Designed for builders who demand rugged performance and dependable components, this Mil-Spec buffer kit is the perfect foundation for a precision AR-9 build.
