Luth-AR 308-CS-10B Carbine Buffer Body .308/7.62mm Steel - AR-10

The Luth-AR 308-CS-10B is a carbine-length buffer body built specifically for .308 Winchester / 7.62x51mm NATO AR-10 platform rifles. Machined from steel, this drop-in buffer is engineered to manage the heavier recoil impulse of .308/7.62mm cartridges in AR-pattern carbines, helping the action cycle reliably without excessive bolt bounce or carrier over-travel.

Designed for use with a carbine receiver extension buffer tube, the 308-CS-10B measures 2.485" long and weighs 3.8 oz, providing the correct weight and geometry for shorter-tube AR-10 builds. It is a direct replacement or upgrade for any .308/7.62mm carbine buffer setup and installs in place of a standard carbine buffer body.

Manufactured by Luth-AR, the 308-CS-10B is sold as the buffer body only and is intended for use in AR-10 carbine platforms chambered in .308/7.62mm.
