Agreed, added the Harris #2 bipod adapter last week and it was simple to do. I couldnt decide if i wanted the bipod closer to gas block or a bit further back, so I mounted the swivel at a spot where i could mount the bipod / adapter forward of the swivel or behind (i dont plan on using that swivel for a sling). I used the Harris Bipod #2 Hollow Forend Adapter - not the 2R, as that is radiused, the #2 has a flat piece that sits inside the underside of the stock.
