Building or tuning an AR-10 platform rifle? The Luth-AR Mil-Spec Carbine Buffer Assembly for .308/7.62 is a complete, ready-to-install recoil system designed for .308 Winchester and 7.62 NATO AR-pattern rifles. Whether you're assembling a new upper, replacing worn components, or fine-tuning your rifle's cycling, this mil-spec kit gives you everything needed to manage recoil and maintain reliable bolt carrier group movement without mixing and matching parts from different manufacturers.
Luth-AR engineered this assembly to mil-spec standards, ensuring compatibility with standard AR-10 lower receivers and uppers. The carbine-profile tube and matched buffer spring are calibrated for the .308 cartridge, so you get proper dwell time and consistent functioning across factory and hand-loaded ammunition. Installation is straightforward for anyone with basic rifle knowledge—no gunsmithing required.
Shooters building duty rifles, hunting platforms, or precision semi-auto systems choose complete buffer kits like this one to eliminate guesswork and ensure every component works as a system. Black finish resists corrosion and blends with most modern AR furniture.
| Caliber | .308 Winchester / 7.62 NATO |
| Platform | AR-10 (mil-spec) |
| Finish | Black |
| Included Components | Carbine buffer tube, .308 buffer body, carbine recoil spring, receiver end plate, castle nut |
Yes, provided your lower is mil-spec AR-10. This kit is sized for standard AR-10 platform rifles using .308 Winchester or 7.62 NATO ammunition.
The assembly comes complete with the carbine buffer tube, .308 carbine recoil buffer, matching carbine recoil spring, receiver end plate, and castle nut. You have everything needed to install a functioning recoil system.
Yes. If you're assembling an AR-10 from parts, this buffer assembly kit provides all the recoil components for the receiver extension without having to source them separately.
This kit is engineered specifically for .308/7.62 AR-10 rifles. The buffer spring, buffer mass, and tube diameter are calibrated for the larger cartridge and different recoil impulse compared to AR-15 systems.
