I got the Harris, it seemed like the thing to do at the time. It's a great little gadget, no doubt, and it doesn't mount on the barrel and mess with harmonics or anything. But the thing is heavy, and it takes a NASCAR pit-crew to get it on and off. And, it's pricey. Recently I bought one of those 3 dollar clip on bipods, shot with it a couple hundred rounds, and it still holds fast. I can take it off and put it back on in about 3.5 seconds. Even if I left it on, it's only about a few ounces of barrel end weight. I'm starting to think a Harris bipod is good for the old BAR's or the SAW or an Armalite .50. I'm not sure it's really a good idea for a mini. But - it depends on how you like to shoot. It's sweet, no doubt. But is it too much? Those other stiff arm, barrel or under barrel mounts are crap. The hex bolts strip with the recoil and they get all wobbly. The old sand bag still rules.
