V Seven QD Endplate And Lightweight Castle Nut – Combo Pack
Made from a super aluminum alloy. 30% Stronger and harder than 7075 T6. Type III hard coat anodized. 5.5 Grams + 6.5 grams for weight.
Very impressed with just how lightweight these are. Two concerns I had were the thin top ring on the QD endplate and the threads of the castle nut. (Given the material) However, both pieces are absolutely rock-solid.
