Work on rossi rs22, 5-star product, but including a manual would make it perfect - ProMag Mossberg International 702 Plinkster Tactical Folding Stock

I just installed the stock on my Rossi RS22 rifle. I have both the RS22 and Mossberg 702 and I can confirm that they are nearly identical. However until I came across another review here that mentioned about loosen one bolt inside the grip, I had hard time installing it. Unfortunately there was no instruction in the packaging and I couldn't find a video on the installation. Hopefully my review adds one entry that mention about the bolt so no one will have to waste that precious 20 minutes I wasted.
