This 12 gauge O/U was brought to me for an unrelated issue to the title which I repaired. However, there are two problems that I now face. 1. When I removed the stock a "square U" shaped spring(?) fell out and I have no idea where it goes. I have tried to find a decent schematic of these shotguns but what I have found are of very poor definition quality and I have been unable to find that part. For all I know it is broken and only part of it is what I have in hand. Anyone have a thoughts about this? 2. I'm not sure of Mossberg's terminology so please bear with me. I tested the safety and it did not work. Upon inspection I found that there is no link from the tang safety button to the "rocker" that swings forward and blocks the trigger movement. I can see no way that the "rocker" is activated, on/off. There is not a single mark indicating that anything is attached to it to activate it. I know I must be missing something but I'm at a loss to figure out what it is. This thing is driving me nutser than I already am so I hope someone can help.
