WE M4 / HK416 Spring Buffer

Im ask in "GBB Airsoft" (vk.com group) "What better and what cause if buffer will be heavу or light-weight?" Most of the answer's will be "Find light version. More gas efficient, less runout for parts, etc.", so instead try to find new one i measure original and recreate in PLA new one. And you know what? Its lighter on 30 grams than original!! But after 10 (or maybe more) mags its almost undamaged. Little scratches, but alluminum buffer has them too. Yes, it's little off size in length, haven't hole for pin, who hold rubber on back side, but look's like its not much need it for now. If someone will have an issue about that, tell me and i make v2 version fo rubber and pin.
