I have not used the product you mentioned, however, I did have an 870 with one of the Remington top folders for a while, I did not like it, it was noisy, kind of flimsy and the way it was made the thin metal stock portion smacked me in the face when I shot it with the stock extended. I think choate used to make a side folder for the 7600, I don't know if they still do or not but their side folders for the shotgun are more comfortable for me. Personally I don't like a folding stock gun unless I am storing the gun in a really tight place, I do like the multiple position collapsable stocks that allow you to adjust for different layers of clothing and such. I don't know if this helps or not.
