I just got my grizzly and it didn't come with a manual lol. It's my first 12ga and I found some helpful vids on YouTube for takedown etc. But I can find any vids or pics on adjusting the ghost ring sight. It's the first ghost ring sight I've owned and any pics, vids would be really appreciated. I tried to unscrew the smaller ones but they don't seem to want to move. So I figured instead of breaking it I'd ask for help lol. Thanks in advance!
