"Cool kit for those with a gbbr. Used this for my WA gbbr m4 franken gun. You can use the complete kit, even the spring. Good recoil, heavier buffer, higher fps, but the spring slaps around in the tube and it's loud. I would recommend it for your gbbr not sure about real steel. I bought two and would buy again if I get another gbbr.
