I use the LimbSaver. A little bulky but works great. Mine is paired with a Mesa Tactical recoil buffer. I took one look at the stock pad and its sharp edges and began the hunt for an AR pad. Honestly, I started to get a little self-conscious of the looks people would give me when I would ask for an AR recoil pad.The combo I have is unbelievably easy to shoot. I was amazed when I watched someone else shoot my 870 as it seemed to kick a lot when watching it, but amazingly little when shooting it. I suspect the Gel-like LimbSaver really helps dissipate the load evenly over the contact area. Very T-shirt friendly shooting.
