RRA 2001 LEGP stock is a full length buffer tube with no slots drilled out of the buffer tube, and a hex bolt and 2 pins holding the rear of the stock on.
The pins and the bolt came out pretty easy, but the buffer tube is worthless.
I was thinking about using the stock on another collapsable stock I had, but it needed at least one more hole drilled in it, and it wasn't worth the effort.
