Luth-AR H3 Carbine Buffer Body

The Luth-AR H3 Carbine Buffer Body is designed to improve the reliability and recoil characteristics of AR-15 carbines, especially those running short-gas or over-gassed systems. Built with three tungsten weights for increased mass, this buffer helps smooth out the rifle’s operating cycle, reduce felt recoil, and enhance overall shooting consistency. It is an ideal upgrade for builders, competitive shooters, and anyone seeking a more controlled and dependable shooting experience.
