This is a Remington 870 stock pictinney stockadapter It comes with a magpul MOE plus. The grip has some damage to the top of it but still works fine. I modified it so I could use a folding Scott the reason I'm not using the adapter anymore. I found 12 gauge slugs a sig folding stock hurts. If you were to run regular buckshot or 20 gauge, folding stock should be fine
