Jesse -
Thanks so much for the quick response and perfect description. I finally understand what that little piece is for...so you don't have to unscrew the cap every time you want to install or uninstall the magazine limiter. That is a slick little piece of engineering. Thanks again you have helped me out a ton. I thought for sure I had lost something in the weeds, but all the parts were there I just had them in the wrong order. It works perfectly now. I seriously would not have been able to fix it at home without your help.
Thanks again,
Keith
