Building a .308 AR platform rifle starts with the right foundation, and the Aero Precision M5 LR-308 6-position mil-spec carbine buffer tube assembly gives you exactly that. This US-made complete buffer tube kit is designed for AR .308 pattern rifles and handles the mechanical basics so you can focus on configuring the rest of your build. The 6-position tube lets you dial in length of pull with your stock of choice, whether you're setting up for prone shooting, tactical work, or hunting from a rest.
The buffer tube itself is machined from 7075-T6 aluminum—the same high-strength alloy used in aerospace applications—so it'll stand up to extended use and still keep weight down at 10.2 ounces. Aero Precision includes everything you need to complete the rear end assembly: the buffer tube, a .308-pattern buffer, the recoil spring, an end plate, and a castle nut. You're just choosing and adding an aftermarket stock to finish the job, which means you get to pick a cheek riser, storage, or ergonomics that match your shooting style.
This is the kind of no-nonsense component that appeals to precision rifle builders and hunters who value consistency and durability. If you're assembling a long-range .308 or upgrading an existing rifle platform, a quality buffer tube assembly is a smart, foundational choice that won't need replacing.

The Aero Precision M5 buffer tube is built for AR .308 / LR-308 pattern rifles. It is not compatible with AR-15 (.223 Remington) platforms, which use a different buffer tube standard.
The kit includes the buffer tube, a .308 buffer, recoil spring, end plate, and castle nut. You'll need to source and install an aftermarket stock of your choice to complete the assembly.
Six adjustable positions let you set the length of pull to fit your body, shooting position, and gear. Whether you're wearing a plate carrier, shooting prone, or shooting in shirt sleeves, you can dial in the exact fit without adding bulk or weight.
Yes—it's designed to mil-spec standards for the AR .308 platform, so it will accept standard aftermarket stocks and other mil-spec-pattern components built for the M5 LR-308 system.
