In my cyber shopping I did see something labeled "oops Kit". It was two of every spring and detent used in the lower. Good marketing, know your customer, Hah!

I once had to put a build on hold for almost a week because I lost the buffer retainer detent and spring... skyrocketed across the shop... like a 79 cent part.
Never again!
