This adapter has a nice wide base to face up to your Harris style bipod. That is the awesome part. I gave it 4 stars becasue the supplied allen wrench or the screws are slightly out of spec with each other and want to start rounding out as you get it good and tight. Don't let this scare you.... just use a good in spec set of allen keys and be careful when "Horsing it down".
At first look it looked good. When I installed it on my rail I noticed it was loose not a tight fit at all.. so I tried to tighten it up more and the screw head stripped out. This thing is garbage. I should have known better. Just pay a little more and get a known brand name. Unless you like something that rattles and is loose, then this will work for you. Typical Chinese junk!!!!!
