Well, Zack, while the purpose of these adapters may be to bypass the weakness of the hinges, they don't compact as far as hinged. I think the two combined would serve me perfectly, because my prob with the stock...err, stock, is that it partially blocks the ejection port (yah, I know, it's airsoft), and that it pushes the stock against the back of my hand when folded. My We G39C had neither problem. To me an M4 stock that folds too might just solve my prob.
And, yah, I look forward to seeing pics of your mod. I've yet to find a good one on Google. I hope it works out best for ya, man.
