I agree. The third strut, which automatically deploys the shoulder pad as you pivot the stock open, is a pretty unique feature of those stocks.
If I recall correctly, there was originally a part of the shoulder piece that was on top (when the stock is in the deployed position) and was rounded to look like the bottom section. This has evidently been removed so the stock doesn't cover the magazine well when folded and it looks like a stick magazine can be used with the stock folded.
Might be a little uncomfortable on the shooting hand with the stock folded, but I think it could be shot that way. There would be no access to the mag catch or other controls, but you could get away with "going gangsta" for one magazine anyway.
