Does anyone know the length of the 231-J stock? Or with a SYE dor that matter. Thinking about the Atlas 4 and it's at 17" I can't remember what the 231 stock is. I kinda think it's 21.5" but I'm not certain and the grounds all wet. If that's the case then with my JBC SYE I gain 4.5" so that would put it at 17"...
