Description

The K-Spec buffer was developed with specific goals in mind reducing felt recoil and enabling faster follow up shots. As modern technology has advanced, many recoil management solutions have been applied to popular pistol operating systems, such as the transition from a single piece recoil rod assembly to a dual recoil rod spring assembly with a compression guide rod. Recognizing the success of this technology in pistols, we applied similar principles to the AR-15 platform, successfully integrating this advanced recoil management system. This results in a smoother shooting experience, minimizing recoil and allowing for faster, more accurate follow up shots. Minimizes felt recoil Allows for quicker follow-up shots Enables faster shooting with improved accuracy A5 style length The buffer weights consist of (2) steel components, (1) tungsten component and a sliding mechanism Finish hard coat anodized in OD green The bumper color is blue Helps eliminate potential bolt bounce Ships with the KAK buffer install tool Comes with a Flatwire buffer spring
