Overview

This H3 buffer is designed for AR-15 carbines using mil-spec receiver extensions. It weighs 5.4oz and aids in reliable cycling with forced reset triggers while maintaining semi-automatic operation - one round per trigger pull. The V2 reciprocating design fits standard carbine buffer tubes without modification. Heavy buffers like this help control bolt velocity, particularly useful with some trigger configurations. Made from quality steel, it replaces standard carbine buffers in any AR-15 platform where enhanced cycling is desired. A drop-in component requiring no gunsmithing, it ships ready to install in your existing carbine setup.
