Description
The K-Spec buffer was developed with two main objectives reducing felt recoil and enabling faster follow up shots. As firearm technology advances, many recoil management solutions from pistol operating systems have set the stage for improvements. A key shift in pistols involved the transition from a single piece recoil rod assembly to a dual recoil rod spring assembly with a compression guide rod, providing more efficient recoil management. The K-Spec buffer takes inspiration from this innovative technology, offering similar benefits for the AR-15 platform by reducing recoil and allowing for smoother, quicker follow up shots. Minimizes felt recoil Allows for quicker follow-up shots Enables faster shooting with improved accuracy A5 style length Buffer weights 3-sliding tungsten weights Finish hard coat anodized in OD green Black bumper Helps eliminate potential bolt bounce Ships with the KAK buffer install tool
