I bought this Ruger PC Carbine a couple of years ago new. I changed out the chassis for an aluminum chassis and a folding trapdoor stock from Midwest Industries. I will provide photos of those products in the listing. I added on a BCM trapdoor pistol grip. Includes a 40 round transparent magazine (reliable). This gun runs flawlessly. It’s one of my favorite guns, I just need to downsize at the moment. This does include the original stock too incase you ever want to switch it back.
