Reviewer: Deb from Monroe, MI United States  
My husband was looking for a MagPul Gen 3 stock to replace the fixed stock on his custom RRA so that I could shoot it.   We had fits finding one in stock but through my search (OK so I really want to fire that rifle) I found the exact one in stock.  I got to brag that I found what he couldn't!  Of course the trick is to get him to let me near the rifle now that it has the adjustable stock....
