I have a black Magpul PRS stock for sale. It is not the newer Gen 3. I believe it is a Gen 2, but it could be a Gen1. It comes with the rifle length buffer tube and the rifle buffer and spring. All are in great shape. This stock has lived on my 6.8spc AR for the last 8 years, but I just switched it out for a PRS Lite.
Price is $200 shipped to your door via USPS with insurance.
