I have a S&W MP 15 and I love it... The only thing that bugs me about it is the collapsible stock, there is nothing wrong with it at all, but I would much prefer a solid old style non adjustable one... My question is what is the length of the non adjustable stock, and is there a particular one that I need ?

I have my collapsible stock set on the fourth click, which makes the length between the receiver and the end of the butt plate 9 inches. I guess I will have to put up with my collapsible stock but I hope I'm wrong.

Please let me know.
